@Stanislav-Damjanov said in Software Update 2.48.16 (2025 November Rain release):
it misseg almost every seconon 25m distance, I counted more than 10 missed distances. My swimning style is exactly the same it was before, and usually it missed one or two distances in about 2.5km.
Yes, the missed lengths have skyrocketed also for me over the almost exactly one year since I bought the Race S. Back then (December 2024) the algorithm categorized everything as "Free"style, but missed very few lengths. Then Suunto started to tinker with style identification…
What is now a fact, is that if the algorithm can’t identify the style, the whole length is discarded (instead of having a fallback to e.g. Freestyle). For me, as a competitive swimmer in the 1970s with Breaststroke as a specialty, this has a profound implication. Back then we were tought a very tight and quick arm pull, something crudely ascii-drawn like:

I am trying to illustrate a sort of < > pattern with the upper and lower arms. Using this style the algorithm discards about 80% to 100% of all my Breaststroke lengths. The watch starts to count lengths again if I use a more modern and wider competition arms style; again crude ascii:

It also count lengths quite consistently if I use the widest style of all, the slow recreational style tought by my father:

Apart from having to relearn a swimming style (!), the problem with a modern wide arm pull is that it relies quite a bit on muscle strength. I am 65, so that style is very exhausting. And even as a youngster the idea of the tight arm pull was to quickly get them out of the way and use the legs as the main way of propulsion.
Anyway, these are my experiences… Since I do about 50% Freestyle and 50% Breaststroke the current situation is really disheartening. Last swimming session I left the watch at home - if it can’t count, there’s little use for it.
