I found this interesting, you might too
Seems high (and so it should given the context) but not completely bonkers, remembering that that's for two hands so it's only 4 catches per second per hand. My 5b lift bounce runs at around 250/min, and it's a pretty relaxed pattern that I'm not trying to rush, I can see that doubling the frequency might be within the bounds of possibility, but at what cost to accuracy?
Don't think a theoretical argument's even needed, with the 3b speed record at 501 and the 4b speed record at 498: https://juggle.fandom.com/wiki/Speed_juggling
I should try to take that 4b record again...
The difference between fastest and slowest is surprisingly small for a couple categories, 6 clubs (233 vs 210) and 7 rings (273 vs 243).
IIRC, a lot of the higher number speed records were just endurance runs by people who happened to be particularly quick or slow jugglers. They weren't going for either kind of speed record.
Yes I think it is safe to say that. Was there any category where the endurance record was just over a minute so the fastest and slowest records were the same?
I'd be interested in how they worked out the data used to plot the success/failure graphs. I only skimmed the paper the article refers to which just says the data is from simulations rather than real world juggling. I'm particularly sceptical of the concept of a single correct angle or correct speed. Are they measuring deviation from a single perfect throw? In a real world pattern the 'correct' angle & throw is dependant on the accuracy of all the preceding throws. This 'correct' throw may be a long way from the average perfect throw but will result in a success, whereas making a perfect average throw after a series of non perfect throws would result in a failure.
However, I'm also confused by all the Y axes being labelled Z, so what do I know?
“Physics Today informs readers about science and its role in society.” The simulations were done by launching the ball at a range of starting angles and a range of starting velocities. “Each trial comprises 50 throws for each combination of v0 and θ0 in the plots. Any throw in a trial that misses a catching hand 10 cm in diameter counts as a failure.” In between the throw and the catch the track is a parabola with parameters determined by v0 and θ0. It is a simple two dimensional model. In real juggling two starting angles (left-right and forward-backward) can vary and the position of the launch can vary and probably other things as well. Still it’s a good start and does show why a shower is harder than a cascade.
