In Coop guides for building, there are numbers. But what to the numbers mean? Minutes can't be right and I can't think of anything that makes sense.
Here's an example
14 Supply Depot
17 Command Center beside Rocks
19 Galleon
I know you don't build 19 galleons because you are limited to 5
Can't be 19 minutes into the game because by then you will have lost
If they have a meaning, then by heaven's sake tell what they mean.
If they are meaningless, they should be removed
I looked a LONG time before posting.
