The reason I ask is because above the tables, there are links to some >>downloads - 1320 Lightning Games etc., etc. 60 minutes + 2 sec/move is not a >>lightning time control. Could I be misinterpreting the 60+2? Should I be >>thinking that 60+2 means 60 seconds plus 2 seconds per move? > >60 seconds with 2 second increments. Then it makes sense that ponder on/off doesn't make any statistical difference. The computer hardly has time to think under that time control. I'm guessing that the longer the time control, the more influence ponder on/off has.
