What charm said. Both the prerequisites and the Killroy70 workout are created off the back of Coaches knowledge. Killroy read a book. Coach wrote that book.
F1 isn't exactly a one-size-fits-all program. You will be working at a level appropriate to you in each exercise. There's wiggle room in the warmup if you need extra work in previous elements.
At the very least with your program, instead of a combined push-pull day I would have a high rep day, focusing on building up endurance in the smaller muscles that cross the joints.
