you are doing many things right. somebody better than i is going to have to take a crack at this. but i will mention one thing i see, or think i see. your hand doesn’t drift down very far, honestly, during its extend phase. for example, you take mr freeze, i like his kick over yours. snappy, gets thrust, he kicks with a purpose. but your extend phase is better. which some people call the glide phase, but then they get shit from the purists who say, “gliding implies you’re not doing anything during that part of the stroke cycle, but you’re in fact actively involved, so, don’t say glide.” whatever.
your hand doesn’t drop as much as mr freeze’s hand. that’s what he’s got to work on, for starters. this is the hard part, and you’ve got this mostly licked. then comes the part that should be easier for you, and this is - from what i can see - where you fail. your elbow is relatively high once you start your pull. good. but the active joint here is the elbow, and there’s no action there. everything for you happens at the shoulder. at the moment you’re done extending and you’re ready to commence the pull, you have to get that forearm perpendicular to the water and that requires a bend at the elbow.
grip it and rip it, as the golfers say, but some swimmers and coaches have appropriated this term because you can’t rip it until you grip it and your problem isn’t the rip. it’s the grip. you, like mr freeze, are muscled and capable. so. imagine you’re in a pool where the water sits below the deck. if i ask you to get your body next to the wall, and hoist yourself up so that you’re resting on your arm - just one arm - and that arm is flat on the deck of the pool, is your arm going to be straight? i suspect not. it’ll be bent at the elbow. you’ll notice that your entire forearm, and at some point even your upper arm, is perpendicular to your body. if you translate that to the water, that’s the grip. that’s the pulling surface. you’re fully perpendicular to the water now.
look at this GTN video.

so, this guy’s the expert. and, a very good swimmer. however, besides what some might criticize as excessive rotation (this is what folks talk about when they mention over-rotation, which is distinct from over-reaching), you’ll note that he has about the same amount of downward drift during the catch phase as do you.
the difference is that when he commences the pull, he’s focused on presenting the largest possible pulling surface to the water, which requires a high, and bent, elbow, and he doesn’t fart around trying to make an S or any of that outdated horseshit. i think you’re full capable of ripping it, you just need a grip to rip. beyond what folks better capable than i might say about your stroke, this is the obvious thing that sticks out. were i you, i might consider incorporating pulling into your swim regime. so, paddles and a buoy. used together. you don’t need a gigantic paddle, or a techie paddle. just a typical, midsized paddle. perhaps you’re already pulling. i just wonder whether feeling the pressure on that paddle, directly, for as long as you can keep that pressure on the paddle, might help you get a feel for the water you’re trying to pull yourself past.
look at the grant hackett video above. then look at any of your (excellently done) videos that show your underwater stroke. look where his elbow is, and what it does. look at your elbow. that’s the big difference between your stroke now and your championship stroke. according to me
