Could we get graph and history of MMR changes?

Dear Riot,

Could you give us histogram of MMR changes with logs on average team MMRs and personal MMR every entry? I know it is hard for you to implemetn such basic database function, but please, surpass your expectations and do it. Reason for this? TO see, if some MMR chagnes are not valid, and also to improve MMR system during placement. It is really werid that I win 7 games out of 10 and end up in Bronze 5 with really low mmr. That mean every los woud be aroudn 200 to 400 MMR lost or every win has almost no if any at all gained. IF starting MMR was 1200, and starign with 4 wins before first loss, means my start wins gained me less than I lost in single loss.

I know it would be hard for you to discuss of this, as the issue has been total embarrassment since season 2. It is really embarrassing to see, that company doing the game has no clue of math, logic, or statistics, but still think those work fine with "professional" assessments like "4 vs 5 is as hard as 5 vs 5 as it could be exploited if it did not": Riot has nto given us SINGLE case how it could be exploited.
