Swim smooth has an interesting pair of videos that makes the argument that minimizing strokes per length isn't the same thing as maximizing efficiency. Janet Evans and Laure Manaudou are cited as examples of swimmers with high strokes per length and a faster turnover. Elite triathletes with shorter strokes are also cited. The idea is not to advocate everyone use a shorter stroke but just to say that if a shorter stroke works for you don't throw that away in pursuit of lower strokes per length.
I wonder if swimming with a shorter stroke and higher turnover is analogous to using a lower gear when cycling (spinning versus grinding). People generally acknowledge that the optimal gear to use will vary from individual to individual. Extrapolating from that line of reasoning, perhaps elite swimmers using longer strokes do so because they have greater strength/more power that allows them to use a longer stroke/higher gear rather than because they worked on lengthening their strokes (although the two are clearly related).

One of the most sensible things I have read on this forum.
I agree that each person will have their own optimal stroke count. We're all built differently and will have somewhat different mechanics. Physiologically different people might also be able to sustain a higher turnover or higher power output than average.
I'd maintain that the basic mechanical motions will still be the same, though, and that the key ideas are minimize drag, maximize propulsion. Stroke length will differ, some people have shorter arms and may be able to sustain a higher turnover without increasing drag, but a nearly optimal basic swimming stroke will be similar with most people.
