Personally, I don’t think so. As far as time goes, if you’re following the rest periods you can finish this in 25 minutes. To the point of the repetitions though, I feel we use our upper body muscles a lot more because they get used as secondary muscles even on days we aren’t training those body parts. For example arms get hit on arm day and then a little on chest day and a little on back day. Legs only get hit on leg day and during deadlifts. So if you counted the reps where these muscles get used as secondary muscles and primary your weekly repetitions for each upper body muscle would be way higher than your lower body muscles. Increasing the reps on leg days will help keep total repetitions equal, if that makes sense.
The reason I do this is because I had a lot of trouble growing my lower body since I started lifting until I did this routine. I’m sure you could cut the reps down a little but there’s something about the insanely high reps that is unmatched in any other leg routine I’ve tried. This routine made me proportionate and made my woman’s legs huge. I’m a believer the legs can handle large amounts of reps, some people’s legs even need it to grow
