I don't have those data. I'm only familiar with the fact that a 5* fast trainer should gain 4 skill points per 15-18 condition loss. If you could let me know how many skill points a fast trainer should gain for a drill that has the average of 0-19, 20-39, 40-59, 60-79, 80-99, 100-119, 120-139, 140-159 and 160-179 I might be able to develop a calculator for your needs. Assuming the rate of rest packs increases with the rate of the decrease of progression for each interval.
If there's data showing how much a player's development potential decreases for different ages, I'd be able to add that as well giving us the option to choose age as well.
