I don’t dare do tumble turns if someone is near me, just don’t trust myself. But I am definitely quicker with them than open turn when fairly fresh. Not practiced enough to get them right tired. Also, have the feeling that I really need a breath when tired. I know it is CO2 rather than a lack of O2 but still.

The tumbling and flipping over but I’m alright at it’s just getting off the wall again, especially facing the right direction. My dolphin kick is also shit. Having said that my kick in general is shit!

As long as you get a decent streamline off the wall dont stress the kicks, even the best distance freestylers are only doing 1 or 2 kicks

I tried to do some of those non-rotating tumble turns today, but water went way up my nose each time. Think being an old dog I’ll stick with the half-twist trick learned 30 years ago

breathe out through the nose, stops it happening

On this, El Niño’s turns were really good from his IM race. 
How you able to video it I don’t know

One of the really noticeable things about doing these 100s is how much I need to increase my stroke rate to hit sub 1m30
This morning was up at 60-65 strokes per minute.
With easy pool access & no real structure to sessions, I had fallen into a lazy habit of just getting in and cruising at say 1m50 per 100 for a steady 1500m, and stroke rate then is more like 40-45 per minute.

His Breaststroke UW are first class, up there with the best but fly kick needs a lot more power to be effective for the full distance. You would have seen, he gets over 10m , but starts to lose a bit of ground on those who breakout a bit earlier. My opinion they do too much “200 fly kick on back” type stuff and not enough 15m flat out
His back to breast is pretty cool, almost a crossover turn but does a backward flip (in IM you must finish each stroke as per stoke rules so must touch on your back before initiating the turn)

We weren’t born yesterday, you just want us to bend down to look at it and we get squirted with water!

Which inhibits tumbling, by nature.

acts as a rudder…for el Nino when H doesn’t allow him to wear shorts…

I didn’t get to the pool last week so by way of reintroducing myself I thought I would do a DPS set last night. Normal 800m w/u then 16x 25m at 50 SPM (does that look familiar?). Tempo trainer immediately gave up the ghost but I did them as slow stroke rate. Pretty please I managed 7 of them at 15 strokes per length the rest at 16. I have done 15 before but never that many. I think the improvement comes from a combination of using the core and rotation to help power the stroke and better timing of my kick (2 beat). I think that they are part of the same thing, in that I don’t think the former happens without the latter. But that is just what I think, rather than founded in any knowledge of swimming.

timing is key I recon, by focusing on the “tick tock” of the rotation you will inadvertently improve your timing, and possibly the lat recruitment
good effort.
how the mighty have fallen, i did 1500m yesterday, 2nd swim in 2 days. I did it all easy, largely sets of 100 off 2:15, 4th length back in most of them, held around 1:45’s

Good work…

What we are discussing is really a case of “models of” and “models for”…
Models for are idealistic representations of a skill or activity. Swim Smooth, for example (other models are available), is a model for swimming. It is an idealistic representation of what swimming should be like based on observations. What we don’t have for swimming is a model of which is an empirically based model that determines that this is the most effective or efficient way to swim.
The equivalent in running would be Chi running or Pose running which are models for. However, we actually have much more data on running and are close to making a model of running.
There will always therefore be plenty of scope for differing opinion about swimming…

Are these seen as “good” models?
I’m not sure there is “perfection” in swimming as we all have different body shapes and sizes.
Two notable cases, look at Adam Peaty’s stroke. No way that ever gets put in a textbook or used as a “model”, but he had up to a couple years back the top 20 times ever swam.
Second for my L1 swim course too many years ago I had to do stroke description and analysis of Michael Phelps. Considering how fast he was, his FC stroke had a number of faults, ie catching too early; common in Fly swimmers, but again the greatest Olympian in history
Now Adlington does have a near a perfect distance FS stroke! but that wouldn’t work for all, look at Ledecky
tl;dr we are all different and there is more than one way to swim fast

Maglischo must be close to that, science backed and evidenced, changed his interpretation 3 times as he has learnt more, to the point he dismissed his first tome. Then again Counsilman had a massively science backed interpretation but much of which (lift and drag based on his observations in aviation) have been dismissed due to the speed of which the swimmer goes at.
I think the closest we can get in it’s purest form is Newtons 3rd law, every action has an equal and opposite reaction.
By the authors? Yes 
aspects of them seem to contribute to good form…but they are far from complete models…
