I think the answer is more complicated than falling into a pigeon hole.
First, later in the thread you said you wanted to "turbo boost performance." Not everyone can "turbo boost" every aspect of performance at every step in his progression. One of the biggest mistakes I see shooters make is thinking that no matter where they're at, there's some special secret or change that will suddenly and magically halve their draw speed or double their accuracy. Do you think Michael Phelps jumps in the pool each morning and says, today I'm going to take ten seconds off my personal record!, folks? No.
At the same time, for every person who wants to discover the magic bullet of instant awesomeness there is a shooter who believes that plodding along at the same exact thing the same exact way every time he goes to the range will somehow make him better. To borrow a phrase from John Holschen, if you always do what you've always done, you'll always get what you've always got. That's where goal setting and performance tracking comes into play.
In my experience, most shooters aren't very honest with themselves. The "go big" crowd often talks about that one time a drill went spectacularly well but forgets all the instances with misses and mistakes and fumbles. Awesomeness that isn't repeatable or dependable isn't awesomeness, it's freak chance. The "slow and steady" crowd often convinces itself that it's getting better but in reality hasn't seen a modicum of improvement in a long, long time. Feeling better isn't the same as performing better.
There's also a matter of practical need. A hostage rescue team guy is probably a lot more concerned about never making a mistake than someone who is primarily interested in IPSC. To him, improvement may not be measured by improving his average El Prez by 1 second but rather by going from 95% success to 99.5% success in running El Prez (12 A's) in a given time period. I've worked with military units who treat a single hit on a "non-threat" as a fireable offense. That means if you hit one non-threat target during the course of an intense multi-week training cycle you can get booted from the team. How would your approach to USPSA be different if hitting a single no-shoot got you banned for life?
Define your needs and priorities. Establish goals to address them. Create a plan to drive toward those goals.
