Greetings blood buddies!

I have to admit that I am horrible in math! I actually got an F- in Algebra! Needless to say I am challenged  and struggle to understand log reductions!

I finally got back to an MMR with my recent PCR and a result of .0956, Yeah!

  My question is why is this a full log when my last result was .257? If my recent result had gone up to .557 it would have been considered statistically the same but not when it goes down? Wouldn't it have to have gone from .257 to .0257 to be a full log? Is MMR just MMR and doesn't matter if the move downward is small?

I think my head is going to explode.....

A log is a factor of 10 (in this context, other logs are available).

You haven't had a full log reduction from your last result, but you have gone below the MMR mark which is 3 logs below the IS 'standard' baseline of 100%  - ie 0.1%

Congratulations.  A great place to be.
