Since March 18, 2020 I have worked more hours per week for such a long period than ever in my life.. But if practice makes perfect, then doing something for years on end and then adding 20-30 extra hours a week for 9 months should make make me dang great at my job. I think I am, but then I see something like this and can only hope to be as good at my job as these dudes are.
I know I am not as good at drumming as that cat here, but to see three such accomplished musicians (and ALL 3 are great) proves to me that the age old saying (look for poor pun included in paragraph) "You don't stop playing because you got old, you got old cuz you stopped playing."
I'm getting the feeling you are posting this because you may be frustrated with the quality of your skill despite the dramatic increase of time invested in it? The number one thing I ever learned was quality of practice/training is much, much better than duration. I don't have experience playing drums, but I do in music production as well as shooting guns. 
What I can tell you is you always perform how you practice. You always default to your training, especially when its spur of the moment. The best advice I can tell you is you end your practice on a high note (pun intended). When things are just working out and sounds and feels great, stop. Don't push yourself to exhaustion and leave your session performing at a lesser quality.
For example, I'll quit mixing a song like in 30 minutes, otherwise my ears get fatigued and i'll start making mixing mistakes after that (but it will SEEM like I'm making quality decisions but with fatigued and misleading ears). So then I'll take a huge break before coming back to it.
When practicing marksmanship, I won't rip through 500 rounds in my Glock with substandard results. I'll stop at 300 when my targets look great.
Your mind and body will remember your last practice. Your muscle memory will also remember it as well. Best not to remember the substandard. My advice is to quit while you are ahead and lock that awesome experience into memory.
Also, always keep your target in focus.... For you, it's your reference tracks like Rush and/or any band that have awesome drummers. Keep listening to them A LOT so when you practice, your mind and body will coordinate to emulate your experience (your best practices as well as hearing what drums SHOULD sound and look like).
In other words, don't practice the wrong way. Don't practice "to exhaustion." You'll just create the wrong neural pathways in your brain. Instead, practice "to quality" and lock in those quality neural pathways.
Hope this helps a bit. It definitely has helped me.
