Have an option for a deload week within a program or at least a so that their weight and reps are not recorded as what they did the last week. Sometimes I do specific muscle group deloads and will accidentally do the weight shown as my last weight so this could be also be fixed by showing the last two weeks instead of just the last week next to the exercise. Or at least a notes section next to each exercise to record that you did a different tempo, used a different attachment etc. so we know why they were able to do way more/less weight.
