I think for a program to have this high a rating (2480) after 10-12 games is amazing how many people here feel they would have the same rating if everyone got to study and prepare against you very minimum your dropping at least 100pts ever go into a lower rated players pet line?? This is what it amounts to. (in my opinion)
