a question: does the new/readjusted schedule still hold true for 'number of matches left to play' on the spreadsheet? like do mbc, ace and fox players still have one less than other teams?

Hi,

Here's a suggestion for allowing trading without introducing -too- much work.

For simplifying discussion say a person only picks two players for main team. Say, Action and Bisu. I suppose that you'd just record the person's team as Action+Bisu, then at the end of Round 2 sum both Action's and Bisu's points to get the person's points.

Now suppose he wants to trade Bisu for Calm and you've checked race/rank restrictions and whatnot and deemed this allowable. I suppose you'd be thinking that to implement this, you'd have to keep track of all progamers' points week-by-week. So my suggestion is how to bypass that:

Just keep an extra variable P initialised to 0 for each person. At the point where Bisu is traded for Calm, take Bisu's CURRENT point B and Calm's CURRENT point C, then update P to P+B-C. Then, remove Bisu from the person's team and add Calm in. Now you don't ever have to record that the person had Bisu and traded for Calm during which week. At the end of Round 2, just sum Action's and Calm's FINAL points and P to get the person's points.

Why this works is that you're effectively keeping B = (Bisu's points the person did get) - C = (Calm's points the person DIDN'T get). When you add Calm's final points at the end to P, you are effectively subtracting off Calm's points he didn't get.

With a little thought you can also see this works for multiple trades, trading traded players, proteam trades, and you can also reverse the signs to make it work for anti-team trades.

The downside is that you have to do this each week, and it would be hard to undo any trades, say a few weeks later, if you find out you accidentally allowed a bad trade or something, unless you keep some sort of trade accounting history.

It's up to you though, just a suggestion, and thanks heaps for setting up this FPL! If you need further clarifications on the method I'd be happy to explain.
