His DPS is incredible. 60spm is very deliberate for a swimmer of that caliber. There’s really nothing remarkable about his stroke. His body position is top notch and i think that enables him to maximize his propulsion… (obvious statement of the day).
Post #8 (and the link) contains some key concepts. Basically, an unconsciously competent athlete is usually not a good coach (should be required reading).
As a AOS I got coaching, but, mostly my success came from: A high VO2 Max, real comfort in the water, and some disgustingly difficult workouts.
I can’t teach anything swim related worth a shit; despite being a corporate trainer for >3 decades

The best ow swimmer I know is the slowest in a 100 of all of us in our local group.
But over a 3-5km race he can hold his steady state very well. The best distance swimmers can sit higher to their top speeds. Just lots of endurance required at the appropriate speeds, not too fast not too slow, to build that up.
Is your top speed or endurance what is holding you back from your times you want
Here is a good one.
To find more (and there are a lot available), what l do is I search ‘800m swimming’ or ‘1500m swimming’ on YouTube. And then l look (within these search categories) for videos that have all or most of the swim footage. And for videos that show some underwater footage as well. Then l set the video resolution as high as possible and try to watch it on a big monitor or on a TV. Then you get a great visual of excellent distance swim technique.
Here’s a good one too. Look at head/body position, almost no kick required, and at a tempo that’s more relatable to us mortals. I love watching Katie Ledecky swim but her tempo is practically sprint for adult OWS.
