My 2 cents:
1) Max effort jumping ( and landing ) is extremely taxing, needs recovery, even more as those joints age and rust. You can't go max jumping every day and expect to be at peak.
2) 5-10 max jumps may be too little volume. You never know when you will 'catch' your best jump. You dont want to overdo it but neither underdo it.
(1),(2)=> Don't jump max every day. Do 1 day jumping and 1 day only bball stuff. No more than 3 max jumping days a week, i would go for 2. Now when you jump, do at least 20 jumps. Do a dynamic warmup, then do a jumping warmup ( 5-10 jumps starting with low effort and then building up ). Then do your max jumping in sets. Like sets of 3 or 4 jumps, rest 30 seconds to 1 minute between each jump, rest 3 to 5 minutes between sets. Do at least 20 max jumps. After you reached 20 jumps, stop either when your max jumps dropoff by 2-3 inches or at 30 jumps.
A 3d cent : Your training goes great currently. Strong, lean, good plan ( strength training + jumping ). Don't you dare change anything scooby, you have finally found a good balance. Maybe just cut the regular 1RM PR attempts. When you reach that grinding rep, STOP, the next failed one does not offer anything, on the contrary. Keep the PR/testign sessions to 1 session per month or something like that.
