the only trouble with calibration is its started to generate more negative results for many players,yes we don't want or need 16-0 results, and i think looking back old results i had, odd times instead of winning a game 8-0 12-0 etc i may have got a result 3-0 4-0 against weaker sides, i now feel those results are now being generated as 1-0 0-0 even defeats such 0-1 0-2
