^^ I have a bit more fat now, and extra water weight too. One thing not to forget: depending on if you're carbed up or not, your water weight and glycogen can fluctuate by 5lbs or so.
So I can actually just eat less for two days, and then stay at maintenance calories and maintain 192lbs. Or I can continue eat the same amount and maintain my carbed up state, and maintain 196lbs with some extra water and glycogen in me. What I used to do is maintain that lower weight... but it makes more sense recovery wise to maintain that higher weight. The amount of fat you have in both examples is the same! So why not have full glycogen stores while you maintain your weight???
Anyway, as for dropping water weight before testing vert, that's probably pretty easy to do. Just cut weight the same way wrestlers and boxers do. Maybe not as drastically though.

Another thing to note is that I feel like I can work out harder when I'm fasted. I feel like I can jump higher in a fasted state. This can be "stacked" with a water cut. Drop 5lbs of water weight, fast the day you want to jump, and stretch those hip flexors before hand. It's surely a nice way to peak your vertical jump... and that's not even adding in any potentiation techniques from the current training microcycle you're in.
