barbell jump squats, jumps with a vest etc

they should have done a P60 also, I imagine that would be better than P45.

Exploring the Optimal Inter-Repetition Rest Duration to Maximise Power Velocity and Force During the Squat Jump
The use of inter-repetition rest within a set (IRR) has been reported to
attenuate the decline in power performance when compared with continuous
repetition set configurations. However, the effect of IRR duration between
single squat jump repetitions is unknown. This knowledge might be
advantageous to optimize power development. Twenty male subjects
completed four squat jumps at 20% of a 1 RM back squat under four different
protocol conditions: TR0 = no IRR between repetitions (reps), P15 = 15
seconds(s) between reps, P30 = 30 s between reps and P45 = 45 s between
reps. Peak force (PF), peak velocity (PV), and peak power (PP) were
measured for each trial. Significant increases (P < 0.05) in PP and PV were
noted during P30 from Rep (R)1 to R3 and R4, and P45 R2 to R4. Comparison
of likewise repetitions across conditions show that subjects were able to
produce superior PP and PV efforts during R4 across all IRR conditions
compared to with TR (Figures 6-8). This was statistically significant during P45
for PV and PP (R4 PP P = 0.004, R4 PV P = 0.002). Mean NET values for the
four conditions show a linear increase in PP, PF, and PV with an increase in
IRR (although non-significant). In agreement with Hansen et al. (19) and
Hardee et al. (20-22), the results demonstrate a positive influence of IRR to
enhance power output. Strength and Conditioning Coaches could use IRR to
accelerate the learning process and increase power during training. Of the
four conditions explored, an IRR of 45 s appears optimal to maximize power
output during a squat jump.

that's my n=1 experience for both SVJ and RVJ.
