I'm familiar with that feeding schedule, too (I'm on the same forum!). I personally think it's too aggressive of a feeding schedule. The snakes get too big too fast IMO. Why the rush to get them so big? I just think it borders on power feeding.
What I do (and have been doing for over 10+ yrs) is to start out feeding 1.5x's the width. Feed that size once a week until the lump is barely visible, then up to the next size, and so forth. I stop at jumbo mice and they continue to get those, even if they're huge.
