I think the whole "bulking up" approach that was gym lore for decades has finally begun to fall by the wayside as more gym goers actually have access to more information than just weider -protein-powder ads disguised as articles.
I agree with the small changes and goals, but even with a 1 lb gain per week, I think you're risking well over a 50% fat gain per month. One of my favorite quotes from Dorian Yates was about how a competitor with the best genetics, the best training, best diet, and best "supplements", can only put on a Pound or two of muscle in a month's time. Now if that's a unicorn-type best case scenario, and an actual new lb of muscle synthesized by the body is at best costing a couple of hundred calories (I forget the exact # at the moment), so long as the gym goer in question is meeting a well planned macro split and getting their micronutrients, and they're not excessively lean (i.e. Day to day looking with enough "extra cals" to not be ripped), IMO they don't even need to worry about a specified weekly gain.
When I was still competing, my off-season weight was the same every year, with no weekly or monthly weight gain goal, and yet when I would diet down, like clockwork I would be 2-3 lbs heavier. Support your training, get enough nutrients for the small increases to occur at the excruciatingly slow pace that they do, and let time do it's work.
I know that newbs need something concrete, but I gotta think that the weekly gain, then scale back when you get too sloppy approach isn't always the best.
