Well I think to get fast you should just not care. Perhaps set a limit to your memo times (if my memo goes above 30 I usually just give up the solve) and just GOGOGO, especially in single BLD. This is often what helps you break plateaus, and after your times generally get faster (with more DNFs) you can start trying to get more comfortable during memo and you'll find that it's easier to do safe solves. So it's more like a GOGOGO, play slightly safe, GOGOGO, play slightly safe kinda process.
It amazes me how different 3BLD is to bigger cubes BLD. I've tried the GOGOGO pacing for bigger cubes BLD, and it seems to most of the time lead to longer memo times and more recall delays. For bigger cubes BLD I've found that I try to go as quickly as possible, but when I feel that my memory is not sticking, I throttle back as much as is necessary (sometimes
drastically so). I then memo at the slower pace until I feel the memo begin to stick again, after which I speed up my pace until I again feel that it's not sticking.
It's funny to me, because this pace doesn't seem to work well for me on 3x3x3. When I use this pace on 4x4x4 or 5x5x5 I often get solves that are really fast for me. When I use this on 3x3x3, I either get solves right around my "average" GOGOGO pace, or slower, sometimes as much as 33% slower.
I wonder if certain people take DNFs differently. To me a DNF is 5-10 minutes of post-mortem'ing to figure out what I did wrong. I
hate doing post mortems. It's like rubbing salt in the wound. Not only did I screw up the solve, but now I have to put myself through this ordeal of figuring out
why I screwed up. In general when I practice I'd rather be solving for as much time as possible; I want to waste as little time on doing post-mortems as possible. I've heard from a lot of you sub-60 BLD'ers that GOGOGO pace is the way to do it, but I imagine with as many solves as you all are doing that you're probably not doing a post mortem on many, or any of the DNF solves? Is that true?
My question is this though. If you don't care about whether you DNF or not, and you DNF a lot (whatever a "lot" means to you) without knowing why, then aren't you reinforcing bad habits every time you get a DNF solve? Wouldn't that drastically slow down the pace at which you improve and break past plateaus?
