If you're not struggling to get those last couple of reps, you need to add weight. I was doing 80 lbs on flat bench when I started. I'm up to 160 now. Remember it's about doing the reps with good form and control. My max press is running about 250 these days, and with moving more to free weight is rising again.
You're absolutely right, although it can be tweaked a little to modify it into heavier weight. It relies heavily on bodyweight push-pull for some of the sessions (which I personally believe are quite valuable for general fitness.) What you're doing sounds better. Moreover, it's geared toward your personal needs (cardiac and skeletal muscle strength). 80 to 160? That's a helluva jump--sounds like it's working well for you!
