How the Arena Calculator Works

The calculator is using the following formula from Blizzard:

X = Team Rating, Y = Arena Points
If X<=1500: Y = 0.22 * Rating + 14
(note: this calculation can go negative, but will be floored at 0)
If X>1500: Y =1511.26/(1 + 1639.28 * 2.71828 power(-0.00412*X))

2v2 teams earn 76% of the points of a 5v5 team with the same rating
3v3 teams earn 88% of the points of a 5v5 team with the same rating
