Good on you for learning and trying this stuff. Keep it up.
To help you learn, unfortunately the data is invalid for your standings pie chart. You need to 1) remove eliminations and resigns (or track them separately) and 2) normalize your data to a common scale.
1) tracking eliminations/resigns
In a 1v1 game, if you're eliminated you still come second.
In a 8p game you may survive and come 4th.
This data alone would suggest your result in the first game was better. Which it's clearly not.
2) Normalizing data
Bit detailed for off topic forum chat, but essentially it's making your positions the same value regardless of game size.
Eg 10p game coming 4th is top 50%, but coming 4th in a 4p game is bottom 50%.
Without these changes youll always end up with misleading results.
So next time you hear someone on TV quoting some statistic, question the data.
Bit intense... does anyone know any jokes?
