I'm not discounting anyone's methods or thoughts here, just providing my own:
I personally think BBers have a tendency to overeat which reduces digestive efficiency and leads to, among other issues, a less than ideal look. I've never been a fan of overfeeding (and I've done lots of it). I never try to eat for size unless I'm sub 10% bf, which is most of the time - because I don't force feed. I believe that it's best to form nutrition needs around LBM and current condition, training frequency and hormonal environment. When lean, training frequently with adequate intensity, and creating an optimal hormonal environment for growth, the appetite should be there and the body should give some feedback through appetite that helps gauge what it's craving. Also knowing our bodies well is key. I can easily tell when my body needs increased protein, carbs, both, etc. For benchmarking, I tend to gain best with my current composition, training frequency and hormonal optimization at 300g protein, 300g carbs and ~50g fats (none added, except a bit of EVOO and fish oil). I'm 200lbs pure LBM at 5'10" and ~6% BF - that's 1.5g/lb LBM for carbs and protein. If I want to up my LBM I add protein and carbs in relatively equal ratio's to my meals and adjust my hormonal environment accordingly.
I've tried eating 1g/lb LBM in protein and eating more carbs ~400-500g. I didn't gain any more fat, and my metabolism was racing, stayed pretty full (glycogen) ,etc but I wasn't recovering well enough. I train 5 days in a row and found that I seem to do better with 1.5g protein/lb LBM under those conditions, unless I want to push carbs upwards of 600-800g per day which I personally believe isn't great over too long a time (may strain the pancreas and reduce slin sensitivity), especially since the only "activity" i really get is in the gym and I'm more or less sedentary at other times. I keep fats low so I can't get the cals from there - best bet was to just up the protein a bit and drop the carbs to more moderate levels. The leaner I get, the more protein and carbs I need, which makes sense because there is less and less stored energy to use on my body (fat).
With protein relatively fixed, I'll have days where I cut carbs down and then load them up. If I go over 2g/lb LBM in carbs, I tend to reduce protein a bit - when loading on Sunday after depleting on Saturday (my two off days. Keeps the metabolism fresh, helps with insulin sensitivity and keeps the body guessing.
I don't really count calories, I just use them as relative figures for benchmarking progress vs. my condition.
Personally, I think when BF rises over 10%, things become inefficient and it's time to diet down and then move cals up again. This "cycling" is much better for rebound growth spurts than trying to constantly push linear growth progress - unless you can stay lean enough and keep growing.
