I thought of doing it for some variation on my normal UB/LB splits. The given percentages are way too low imo. The whole workout looks like a DE workout.
So I don’t know if I’ll get something out of it after the 4 weeks.
Sheiko is powerlifting system dominated by great volume of strength training. This is why percentage is low. I have no experience with Sheiko, but IMHO if you increase the percentage, you may get overtrained with such a volume of lifting
Each workout had a certain intensity zone that was defined by the number of reps, and the goal was to complete as many successful lifts during the prescribed time frame.

While several rep schemes were used, the basic three cycles looked like this:
