I had a similar experience with his big bad bench program years ago, but in looking back on it, it was because of my lack of understanding.
I think you can use Dave's progression and speed work, but you may have to pick different ME exercises, maybe different accessory stuff as well. Dave has written that his lockout has always been his weak point, so 3 boards, pin presses, reverse bands, whatever he's got in there, make sense for him. If you're weak off the chest you may be better off with illegal wides, inclines, cambered bar, etc.
Just my two cents, I really didnt "get" this when I was running westside years ago, and havent gone back to it since, but this is what I'd change if I were to do so
