Revise overtraining protection for split programs

I split my workouts in two workouts UPPER and LOWER. I think many
others do that, even splitting body in more segments. It seems the
machine is not aware whether you work your entire body, or you do
"UPPER" one day and "LOWER" another day. Every time I do a workout
(such as UPPER), the next day (when I want to do LOWER) the machine
admonishes me that "it doesn't make much sense to work out today since
you worked out yesterday". If this is done on purpose, specified by
your training method (let one day elapse between workouts even when you
work only a part of your body), than this is correct. I however doubt
that you advise people who workout body parts to only workout every
other day. That way in a week you get very little exercise per body
part. I rather think that this is due to lazy programming. An AI
(Artificial Intelligence) program like Dr. Muscle should have enough
intelligence to know if it is OK to workout your body part today today
(or not). Easy to program. Perhaps you should add some of your science
here to make this a useful feature (that you can advertise: "Dr. Muscle
will detect and let you know if you are overtraining") . After so many
consecutive days of workout without a pause day, and/or if the program
detects a decrease in performance that may be due to overtraining, at
that point the program should discourage the user from doing a workout.
