Anyone up for an experiment?
I have created an algorithm that can predict your "max sustainable pace" for sport-specific movements (like RMU, burpees, box jump overs, light TnG power snatches, etc). I'm really excited about the prospects of this... but I need to gather data. The tests are simple, Day-1 - 1min max rep of the movement Day-3 - 5min max rep of the movement For example Monday - 1min max reps RMU Wednesday - 5min max reps RMU These need to be done in a low-fatigue environment so before metcons / etc within training. All I need are those two data points and I can provide you with some really cool data that you can use inside training and competition. The movement selection doesn't matter as I am (fairly) confident that the formula I've come up with will predict sustainable rep-rates regardless of the movement. If anyone is interested in participating... let me know (1) what you're planning to test, and then (2) just upload your results directly here.

I have some data for you since I’ve done these tests before. Here’s my ring muscle up results: 16 for the 1 minute test 42 for the 5 minute test

@Kyle Ruth awesome thanks for the data. In workouts I do probably average about about 6-8 reps a minute depending on fatigue levels and volume of reps.
The Split Jerk is F@#ing hard
I’ve more or less spent about 12 years lifting…but I still suck at the split jerk at heavy loads. Lighter loads is okay, but once I go beyond 70%, my foot work and pressing turns to 💩 My best clean is 155kg, but my best jerk is only 125kg. And even that weight is a bit iffy. I know that my knees cave in on the dip and my shoulders don’t really lock out. I try to control it but once it gets to a certain load, it’s almost like my body can’t handle it in a way. Any feedback here? I’d love to hear everyone’s thoughts.

I’d play with some behind the neck split jerks at 75% up to eventually 100-105% this way you get exposure to a straighter bar path. Jerk recoveries at 90-110% can be helpful too if you’re having a hard time with confidence when the weight gets heavy.
