I have been keeping track for some time. The results...note, this does not include players that ended up 100%:
When ahead by more than 20 percentage points: won 7 of 13 (54%)
When ahead by less than 20 percentage points: won 9 of 22 (41%)
Total when ahead (including 3 ways or more) won 16 of 35 (46%)
When behind (including 3 ways or more) won 8 of 23 (35%)
