Here is my data for 20 games on my 1100 account and my 64 account.

and here is the screenshots for those games:

Results:
1100 avg teammate level: 365
1100 avg enemy level: 285
00 avg teammate level: 247
00 avg enemy level: 246
and this is on the LOW end, the very bottom as I counted in hundreds instead of being exact. The average level I saw was 400 for my high end account and 200 for my low end account. The low end account also had substantially more leavers where my higher end had none.
