I'm 46 years old and my fingers and reaction times are not what they used to be so, for a pure TPS event such as 2x2, I'm very limited in that aspect.
Ah, I'm a 14 young puppy still with quick fingers and a sharp young mind. Though I think that even without insane TPS, one can still be sub-5, or even sub-4.5. Of course to compensate for a slower turning speed, other things will have to be eliminated and heightened, namely pauses and look ahead.
Regarding 4 (practice) I don't do as much as I'd want because of too many events and too little time.
And, if you want sub-5, effort (practice) will be required to decrease times. Try and decide what events you really like the most (I have 5: 2x2, 3x3, 4x4, OH, and Feet). Prioritize the practice of those events. And of course, practice smart. Look ahead/efficiency and more alg subsets are something I think are what every one can work on. Lookahead is vital for quick intuitive portions (CF) and Algs are necessary for algorithmic portions (OP). Don't just to solves over and over, thats a waste of time. But if you are just doing this for fun, a less intense approach could be take.
I'm young and want to become world class at my favourite events and think that I can. But if your goal is just to become a decent speed, then simply doing solves should definitely do it.
Ah, I forgot about that, thus the title. My mistake.

But both algs are 2-gen and therefore don't mess with corner permutation, so the idea can still be applied for both algs.
I long since realized that R2 U2 R' U2 R2 works the same but leaves the top layer a U2 away
I actually hadn't realized that, I'll try to do that in my solves.
Have you thought of maybe learning a couple OLLs per case with different CP to have more flexibility? (like with the lefty sexy-sledge)
The lefty sexy-sledge thing is actually a COLL thing I use on 3x3 to solve. But no, I don't think it would be worth it. The reason it can be expressed as lefty sexy/sledge is because it is nothing new. The only thing different is the "lefty" part.
Basically you just described learning half of CLL. The thing with lefty sexy/sledge, is that its really basic and simple. That was the idea of my post. None of it was new alg sets, just little simple things that could help but wouldn't require a whole lot of effort.
Also, something I just realized, for when you get a top layer skip (which you may be able to influence) and still have a T/Y perm on the bottom, instead of doing an x2 or z2, for Y perm, you can do R2 F(B)2 R2 and solve the bottom, and unsolve the top.
For T perm, if a pure x2 would position it, an R2 would also suffice. To add on that, you can cancel the first move on the Tperm (sexy/sledge F R U' R' U' R U R' F') and just do an R' to start the alg.
