I was under the impression that KGS gives no assistance with lag  
except in sometimes when passing.

I probably overengineered my time management, but I measure the lag,  
time left, and moves remaining while the game is going on and adjust  
my safety buffer. Ending a game with 3 seconds left (like occurred in  
the tornament) is not atypical for me. I lost a game on time in this  
past tournament from poor undo handling (losing more than a minute)
