kind of interesting...
perhaps you should make separate columns for cost-effectiveness when dealing full splash damage vs no splash, and cost-effectiveness vs armored vs light (for appropriate units)
also the disclaimer about shields isn't really necessary - shields aren't necessarily better than terran/zerg hp because of the way P upgrades work, T repair/medivac heal, and Z regeneration
|
I dont know if this will make any difference, but you could think about the food cost. 1 supply depot costs 100 minerals and gives 10 food. 1 marine costs one food, so thats a costs of ten minerals. 1 marauserd 2 food = 20 minerals 2 BC costs 6 food is 60 minerals.

Protoss shields recharge fast outside of combat in SC2. That can be a big deal, particularly in early game.

Except supply depots actually give 8 food. So marine=12.5 minerals marauder=25 minerals and 1 BC is 6 food=75 minerals.

While the critics are right that the numbers are misleading by themselves, these numbers are always still interesting and give some insight. One of the best uses for these numbers would be for base killing. It's much more simple and the things you need to keep in mind are (which is actually turning into a huge list... but it still seems simpler than a battle army to army):
- buildings usually have 1 armor, meaning subtract a little from your low dmg slow attack rate units. - can the units get into the enemy's base? Cloaked units like the dark templar or banshee for instance. Blink stalkers + observer. Quick hellion run by or reapers. Air units like phoenix. - how much movement do they need to kill workers or buildings (i.e. marines are way more effective than zealots due to range, focus fire, and later on stim + medivac)... demonstrated nicely by game 2 in TLO vs Tester in Day9's king of the beta. - how good the units are at killing static defenses, like photon cannons. Ranged is better due to less static defenses reaching you at any given time. Survivability is a big deal here, like zerglings vs photon cannons or a bunker being repaired. Planetary fortresses get repaired. But if you bring High Templar you can psi storm the workers or an Infester and you can stop them moving to go repair. - how easily the unit can escape when defensive units show up in numbers. Fast movement and cliff walk or hop as reapers and stalkers. Flight like banshees, voidrays, or vikings. Several fit into convenient transports like hydras in overlords or marines in dropships. Can the transport get away? That's easier with more vision, more units to scout, or ranged units to attack from a distance and put the transport less in harms way.
Hell, after all of that it's easier to just say harass with:
- reapers, hellions, dropship marines/marauders, siege tanks/thors/colossi/vikings on cliffs, vikings, banshees, auto-turrets - stalkers, dark templar, voidrays, phoenix, high templar drops on workers, immortal drops early on, forcefield drops (block ramp or mineral line) - mutas, infestor (infested terrans), burrowed roaches, baneling drops on workers, nydas, hydra drops
Kill buildings with: - marines, banshees, battlecruisers, marauders - voidrays, immortals) - hydras, zerglings, roaches, ultras, broodlords, banelings - whatever is convenient If you have your whole army in their base from a recall, use the whole army. Just hope you can get out alive or nearly finish them here.
---out of time sorry for any typos, incompleteness, etc.

@Nihility: Except that you only need to factor in the food cost fully when expanding your army at the start. If you're replacing stuff that's just been destroyed, which happens all the time after the first few units, the food is already there.

I'll make a totally separate chart to factor in supply.

Speedling refers to zerglings with move speed upgrade, crackling refers to a zergling with the attack speed upgrade. You could just list it as zergling with adrenal glands/attack speed upgrade, if you want it to be obvious. Viking air attack cooldown is 2 seconds, not 1. Hellion vs light is not 18 damage, it's 14 without the preigniter upgrade and 24 with. Thor ground attack cooldown is 1.28 You're rounding too much. For example: the SCV has 54 in the last field, but should have 60, which is more than 10% difference.
Marines/marauders with stim/shield are still missing.

Adding to todo.

Let me get back to you on this.

Nerfing Missile turrets would make TvT more interesting and make Mutas less useless, since they get pwnt by missile turrets and pwnt by Thors.

They are switched(by "it's correct" I meant that liquipedia is correct, not the spreadsheet) Assault Mode/Ground/Machine guns should be 1 second(instead of 2). Fighter Mode/Air/Missiles should be 2 seconds(instead of 1).
So actually you didn't make a mistake at first :D

I did something very similar to this in the early beta. I'm pleased that you and I used the exact same formula for unit performance, right down to the exponent!
My summary is also very similar to yours. Zealots are amazing, Tier1 units are by far the most cost-effective units. Terran units are squishy. Mutalisks are actually not good at all.
Of course these numbers are inherently meaningless because they ignore AoE, Armor, Micro, etc. But I still think there is solid value in at least understanding how good units are relative to one another.
One thing you might consider doing next is a more complicated analysis of performance based on HP of a unit. 10 Marines v. 1 Thor, for instance. Each Marine dies quickly, gradually lowering their output overtime. The thor, however, keeps shooting 'till it dies. If you visualize this on a graph, The marines' output over time would be a descending staircase. The thor, however, would be one big box. If you analysis 'performance' as a function of the area under the line, your numbers will start to favor high HP units (Thor, BC, Ultralisk) over Tier1 units - regardless of things like Armor and AoE.
Nice work!

This makes less and less of a difference the bigger the armies are. For example: 1 carrier beats 3 vikings, but 2 carriers lose to 6 vikings, 3 lose to 9, e.t.c.

I'm not sure if I like your interpretation of cost-effectiveness.
Dividing by R^2 should come naturally as you're calculating each in terms of resources. I see the equation as (DPS/R) * (HP/R) - it seems more reasonable to think of it that way, but the problem is that in the end you get some nonsensical units. I'm uncomfortable with is articulating HP as "more time for the unit to actualize DPS," especially as the reasoning for multiplication. In the end you get some sort of Ambiguous HP^2 value (who knows what Damage*HP is supposed to mean) per second per R^2, that is: AHP^2/(S*R^2). I don't think this expression makes any sort of sense logically.
Here's my counterproposal: define unit HP in terms of time as well against some other unit X and determine individual cost-effectiveness unit versus unit. Then the equation should turn out to be D/R, where D is the damage it inflicts over its entire lifespan (continuous fire). There's a few more kinks in this system what with the inherent flaws of using DPS as a standard of measurement overall (damage is done in discrete chunks, etc.) but I think the numbers will be more accurate.
It should tell us certain things we already know (marauders bad against immortals, etc.) but in the end we can also do some analysis on the numbers as a whole for all of the different unit matchups to determine overall cost-effectiveness. It will take longer, but with the marvel of modern programming not too long. Let me see if I can't get started on this.

I just give an exemple with so much theory craft is useless.
Mutalisks appear rather costly, throughput-wise. With their very high speed and very low range, their are very good for harass et just bad (compared to banshee for example) for big fights.
In game experience is the only valuable ressource. There are just too much parameters to do this theory craft.

I really like these charts and great work, especially with listening to others to improve the charts.
I just have some suggestions. Since we are dealing with cost effectiveness of units maybe you can use a separate chart to compare the cost effectiveness of upgrades. For example, Stim Pack, Zealot Charge, Storm, and Hunter Seeker Missile(I especially want to see this one)
Should be pretty easy since you already have the data for units.

So actually you didn't make a mistake at first :D Eh, liquipedia says fm = 1 and am = 2. And I'll work on that rounding. Google's doing some weird stuff there.

Personally, I don't have time for a project of that magnitude, but for you: I say go for it. That definitely sounds like a great way to evaluate units (on a matchup basis). I will have been glad to have prompted you into thinking about it. =]
