For me it is not practicing enough. When I practice I do not practice spares as much as I should. Therefore I go to league/tournament and have a bad game because I missed 1-2 easy spares and instead of shooting 200-220, I shoot 170-180. Over the course of a season, thats a lot of pins to be giving up. Poor timing contributes to bad shots which could lead to washouts/splits which also leave open frames up and avg's down.
