Looks very similar to the Lopez protocol:

My own Lopez derived regime, employed when enthused / ovewhelmed by the difficulty of a project, is to calibrate by finding the max added weight for a 13s hang. Then, each session, after a suitable warm-up (I do 6x7/3s repeaters on a 18mm edge, followed by the same on 14, 12, and 10 mm edges) I do a progression of 10s hangs at 50%, 80%, and 90% of the max.
The meat of the session is then 10s hangs at the max added weight (as many as I can manage, generally 5-8).
Every 3-4 weeks I change to a different sized hold (I tend to alternate between 18mm and 12-14mm - any smaller and skin loss / pain raher than finger strength seem to become limiting).
Main problem using big holds is that the amount of added weight for 2 arm hangs can become intolerable. I had a few sessions of putting on the weight belt / weighted harness etc, falling over, and being unable to stand up! One-armers with a pulley and assistance are more comfortable - the sessions just take a little longer.
Currently in such a "max hang" phase, scared into it by how weak I feel after a long hiatus from fingerboarding (just used a woodie instead over winter). Thankfully, I am slowly reverting to my old marks. When I do, given that I have a power-endurance project, I think changing to Probes' 5x5x5x5 routine would be appropriate - I recall that programme felt horrendous, which suggests it was beneficial! Incidentally, although the calibration routines are different, I found that the actual amount of added weight (or assistance for one-armers) was similar to the Lopez routine (i.e. similar added mass for 10s hangs 3 mins apart and 5x5s/5s repeaters, 5 mins apart).
