I appreciate it. You're right, I know my athleticism will get me farther than most of my opponents so I force my opponents to truly beat me. At singles state in late 2019 pretty much every match I won the first set 7-6 then blew them away in the second set because they were exhausted.
"Singles state" meaning HS championships?
Yeah, I really do need to learn to lob. It's going to be the biggest inhibitor to me getting to 4.5
@OnTheLine can provide a testimonial on the value of the lob.
It's really not that hard to learn: if you already can hit a BH slice [use a Continental grip], you just need to modify the swing path, racquet face angle, and ball trajectory. While that might seem like a lot, you can do progressions: start out hitting a regular slice and then start altering variables. You'll find that as you change one, the others will naturally tend to change too. If you don't, you will hit long.
To use a golf analogy, think of moving from a 2 iron to a pitching wedge in stages. The 2 iron has a low trajectory and moves relatively quickly towards its destination; a pitching wedge has a high trajectory and moves relatively slowly.
Hit a hundred and you should have a pretty good idea of what needs to be done. And you can do this solo with self-feeds. Even better if you have a very high wall to hit against.
Then progress to working with a partner: lobbing every ball might get boring for him so maybe do a normal rally and every 5th shot or so, lob. If you can get it high or deep, that's good enough to neutralize just about anyone at 4.0 and even many at 4.5. If you can do both, you're golden.
FH might be more difficult because not everyone slices much with the FH.
As one old saying goes, "In tennis you need a nice hard drive and a nice soft lob."
For example:
