This one program was amazing, no doubt. But there is one inconvenience that i don't tend to see with other programs, and it's variety. The majority of other programs have variants for hypertophy or strength gains, as also day splits, and it is true that this one is quite versatile on itself, and it's also been done on the early days of Jeff doing such programs, but it could use some kinda variant, pointing to the kind of gains, or the splits, or both, not even on the same program, just another one. For example, this one program seems to be focused more on hypertrophy, but women in general aren't that much interested in forearm hypertorpy, but they are on strenght gains for forearms, so maybe a variant on that could appeal to another kind of audience.
I know, making variants of this kind of program would be way too easy and absurd, you could sell all variants on one package, but also, the existence of programs come from making it easier for the costumer, which basically doesn't wanna learn all that Jeff has learnt, and just want to focus on doing whatever they have to do for their purpouse.
Hope this helps!
