Keeping it off is better than using a setting that feels unnatural.
Incorrect, I also actually have the g5 and used to play with it on 2000dpi thinking the same thing but then read the following and reset it to 1200dpi@1000hz. It now performs much better.

Well not actually incorrect as its all personal preference but having played with very high dpi to low dpi over an extended time i find the higest dpis to hurt my performance. The training exercise they mention is an excellent method to determine what is comfortable for you
