At 2000 my stats for silver and gold were 2.25 & 0.05 after my last 1000 they shifted to 2.23 & 0.06
almost identical to the wiki's 2.38 & 0.05
but my silver seems to stay lower than theirs and gold can jump around easily without a very high sample size.
My iron is lower and bronze higher by about 3 points each.

I know this is mostly academic and the difference (if any) is small, but by my 3000 sample size their numbers are off and I still want an idea (even if I'll never get one) of plt & blk %.
