Give progress in percentages only after the third workout or so

When I have used an exercise for the first time, the app congratulates me for an increase of 3500% in weight, or something similar, when in reality there is no previous record for the exercise. It would be way better, if the app would just say that there is not enough data to determine the progress (and even then, it would give the percentages only after the third workout or so, because on the first workout, the weight might be too light and it can take some time to find the right weight). For example, at the moment the AI tells me that my average 1 RM increase has been 3931% over the past few weeks.
