Not sure what you want to do with rep max, but whatever it is, I recommend that you submit your suggestion at Share Ideas | Garmin
Otherwise, as for the question in the opening post, the reps are used for example when calculating the total weight lifted during the workout as shown then in the activity stats.
And besides that, you can also see statistics of reps for individual exercises in the Reports. So for example you can see how many push ups you did each month during the past year, (and similarly for other exercises and periods).
They introduced it for a while now for a few selected exercises, the basics: bench-press, curl, squat, hip thrust and some others.
It's called benchmark exercises that are influenced by your personal records. You get 1rep values, you can manually link it to other variants of the exercise and use it in a pre-planned workout, like use 80% of benchmark (1rep) weight. So this should over time increase automatically as you progress. I still do it manually though (as you also can't setup the steps according to available plates, and I like my numbers precise and don't like manual corrections after exercising, I can't put on 133,3kg).
But there are still no meaningful statistics to evaluate your progress besides those numbers raising on a few selected exercises and you don't get a graph showing their increase over time.

Check out the Reports section - you get graphs both for the number of reps of certain exercise, as well as the volume (total volume lifted). If you'd like to see anything else, suggest it to Garmin at Share Ideas | Garmin
As I mentioned to you before these are not useful values and they aren't even presented in a useful way.
Yes, but you did not tell what you are looking for. What numbers are useful, and how do you want to have them presented?
Once again:
