I think you guys are still missing the point. I have elaborated on this idea on this board several times now. If, as a novice, you are gaining your 15 lbs per week in the squat and 7.5 lbs per week in the deadlift, powerclean, bench-press and press, you are fine, regardless what you eat. If you stay on your baseline bodyweight, or gain 2 lbs per month, and make ridiculous gains, that is really great for you if you are not also interested in gaining size.
But here is the problem: There are a ton of people that struggle badly to put on strength. And eating more helps them. Now, how MUCH more you need to eat to make consistent progress varies greatly across individuals but can really easily found out via an iterative approach. If you get stuck or can't recover as you should, just eat little bit more. That is not what Rippetoe generally advocates because he knows from experience that people on the internet are usually too dumb to make this happen. So he recommends to just do GOMAD
in the case of underweight, young males because this takes care of a large percentage of the necessary calorie, fat and protein intake. So this is the fail-proof approach and guys that follow it and train accordingly make really impressive increases in strength. In fact, they maximize their strength increase, which is really the point of Rippetoe's SS program for novice trainees.
The truth is that guys afraid of losing their abs often are not able to do either of those things. And that is not some kind of dogma made up by Rippetoe, this is just an observation that can and will be made if you are looking.
To address a few specific points:
THERE IS A HAPPY MEDIUM BETWEEN NOT EATING ENOUGH AND BLOWING UP LIKE A FUCKING TRUCK TIRE.
I agree. But the happy medium will not be able to maximize strength gains. I am not suggesting that everyone has to milk out a novice progression to the last pound via eating a ton. But it is helpful to put ones own progress in relation to those that do and see if the typical difference might be worth eating more after all. It is an individual decision and the end of a novice progression is determined by the outcome of such decisions.
I don't think you realize how much muscle tissue 2 pounds is. Along with that 2 pounds you're holding .8 pounds more glycogen and 1-3 pounds more water. This is without any fat. That's a ridiculous amount of weight gain when you think about it. Over your time lifting you're not going to put more than 30-40 pounds of MUSCLE on unless you're on steroids. Powerlifters and Bodybuilders are all on steroids and this seems to influence people to think you can gain ridiculous amounts. Look at any natural bodybuilder (ones that are actually natural, not ones that compete in natural bodybuilding), and you'll see they aren't really THAT big.
And I agree beginners eat too little, but they don't need to get fat to get strong like you said. They don't even need to lose their abs which Rippetoe seems to think is ridiculous.
Natural bodybuilders do not maximize muscle mass increase due to the demands of their competition. Nor do weight-class athletes in other sports. That makes these populations a poor example to demonstrate your point.
If you want to make a point about a maximum possible LBM increase of X lbs per month, then post the scientific evidence and we can discuss whether that conclusion can be validated by the studies methodology, statistical analysis and actual results.
I'll speculate that if you're eating 7000 calories a day to gain mad weight, first thing is don't do that. But if you will do it regardless like the guy in the picture, you should do a bodybuilders high volume hypetrophy workout with a zillion sets to gain max muscle, a few sets of 5 will not get it done as well. Or maybe you should do the 5s first, and then the extra pump work? Dunno. At least this approach will burn more calorie spending 2-3 hrs in a gym per session and the rest of the time stuffing your face. All I know is the rip faithful walking into the gym 3x a week and not doing anything all week but a few sets of 5 while eating 7000cal will get really fat.
You are actually not aware how hard a couple sets of 5 get at the end of a novice progression. You speak from a standpoint of lacking experience and you are not equipped to have this discussion with us in other regards as well. Do yourself a favor and educate yourself before you bubble this bullshit.
