Not necessarily. Many more factors in play as you know. I had around .750 W/L in league and tourneys last year, with several semi and finals appearances, and didn't get bumped from 3.5 to 4.0. I fully expect to get bumped up this year even though my W/L sucks (around .250 (?) as of today but I only played 4.0 leagues/tourneys, no 3.5).
Anyhow, the OP seems to be more interested in improving to 4.0 level as opposed to being bumped... related but not the same. Lots of good advice in this thread. I have no recipes but will mention one random thing: I find hitting self-fed shots (drop-and-hit) very beneficial, more so than wall or even ball machine drills.
