I feel a “rhythm” with my 6 beat kick for middle-distance (200-500 yards), because not each kick is the same intensity. It’s medium-medium-HARD, medium, medium-HARD. But to me, a distance-swim 2 beat kick is not really “rhythmic.”
In a 2-beat situation, it feels to me like I’m using the kick to help me “get over the hump” of the stroke. I know, that sounds weird. But when the stroking hand is coming past the shoulder, the stroke goes from a “pulling” to a “pushing” motion. That transition is the “hump,” and a kick on the stroking side helps get me over the hump. Simultaneously, I’m using the kick to power rotation to the other side, driving the spearing hand farther forward. If you don’t feel the “getting over the hump” description is working, you might key on that sensation (driving the spearing had forward with a kick from the opposite leg) to develop the timing.
If you are pulling correctly, this so-called “hump” should not even exist at all. The pull to push transition should not even be noticeable unless you really think about it. You want your arms to accelerate during the stroke from slowest at beginning of the catch to fastest at the end of the stroke at your hips. Thus there should be no “hump” in the middle but rather you should be simply trying to accelerate your arm as fast as you can.
There is a real change in the muscle group recruitment allocation in the pull-to-push transition. If you think about it, you may notice it. It happens to, more or less, coincide with the proper time to fire a kick. For someone who’s having trouble timing the kick, it might be worthwhile to try to identify that point. I call it the “hump” not because the hand stops or even slows there, but because it’s roughly the point where the stroke is the deepest, and it’s just before the point of strongest acceleration of the stroke when the kick engages.
With a properly timed kick, that transition can feel kinda like the moment you crest a roller under power on the bike. You don’t slow or hesitate at the crest. Assuming you keep your power constant, you actually start accelerating before the crest as the grade gradually decreased towards zero. As you crest, or “go over the hump,” your rate of acceleration increases noticeably. If you time your kick correctly, and have good body rotation, you can feel a similar increase in acceleration with you stroke at roughly the point of the pull-push transition.
Two things: First, if what you described really happens, wouldn’t this lead to a jerky stroke with constant accelerations and decelerations??? Second, your theory assumes that the swimmers has a fairly strong kick, such that one strong kick by a single leg, actually propels him/her through the water. While this is true for elite swimmers, most tri swimmers barely move when kicking hard with the k-board, so I can’t see how the kick is going to help him/her much at all. And, if the OP were a naturally strong kicker, e.g. kicking 55 sec per 50 yd, or faster, without strain, then I doubt he would have started this thread.
Personally, I think the best advice was given by zentribrett in the first reply to this thread: use a pull buoy and tie your ankles together and just get your legs and feet out of the way. The only slight modification I would add is that the OP does not need to tie his ankles together so tightly that the ankle bones bang together but rather leave about 2-3 inches between the ankles which is the natural distance between ankles if swimming with just the buoy and no ankle band.
