I'm not into that putting stats but I know that it is difficult to interpret.
Yes, there may be something odd, but I won't replace evidence by assumptions for any accusations, let alone a severe attack which is happening here.
andyson: You do know that once you change tiers your average will still go up and down until you reach a set (but unknown) number of ranked rounds? He's only had 40 rounds as a TP!
I know these facts, I know the calculation, and I know that number which is far less than 40. I calculated his average to the point where he is, and I know that there aren't any 43 or 44 scores in the calculation.
And I repeat: Further to only a few of those low rounds he will be a Master.
Now, you talk about unknown numbers and present a freehand interpretation of a difficult stats.
What are you talking about, after all?
