Ok, I’m currently using the test month of Connect+ and am making use of the food logging. I also have an Index S2 on which I weigh myself every morning. The last couple of weeks I regularly noticed that, after my weigh in, I get another weigh in moment. This with a different weight.
Now going through the connect+ Food settings/Food plan I noticed that incorrect weight there as well. It seems the start weight there is not linked to the weight as registered by the Index S2 but has to be entered manually. So every time you adjust the calorie goal, the desired weight loss or something, this weight is pushed to the entire connect ecosystem and to your user profile (also in the weight settings of the user profile of the watch). Without any insight in all the logic of the underlying algorithms I can imagine that this could throw off calculations for VO2max, runpower,…
Seems to be something that could be designed better. Maybe not relevant if you fluctuate around a stable weight, but in case you lose a lot of weight this can be an issue (and as well a puzzle to figure out where these additional weighings are coming from)
