My opinions on the matter are pretty controversial. I think it's near impossible to overfeed a 0-6mos old BP without regurge. I also think if it's working for Wilbanks, there has to be some incredible wisdom to it. What I do with my holdbacks has some overlap, though I have never tried to that extreme. I think part of what makes it work so well for males can work just as well for females in that part of their life, but females just need to reach a larger size, and this heavy feeding needs to be discontinued long before the females can reach breeding size to avoid negative health consequences. Still, a female fed this way up to 6 mos and then slowed down still has a huge advantage in size over a female fed the traditional way. Whether or not you breed a female at 18 mos is a different story. If you continuously breed them and do not allow for them to keep gaining size, they are going to keep having smaller clutches. Their growth potential does slow down more and more over time, so breeding that first possible opportunity is going to set you back for a couple years. You would have to give them 2 or 3 years off to allow them to catch up with the others.
I have had very positive results feeding reptilinks as well and seeing incredible growth rates. Makes sense to me that being so much less taxing on their digestive system, they are able to use a higher percentage of those calories for growth. Getting a BP to eat reptilinks in the first place is not for beginners though. I've done some experimenting with clutch mates where one is fed reptilinks and the other is fed rodents with the same weight, and while my sample size is pretty small, reptilinks has been the clear winner out of each pair I tried.
