The more I'm thinking about this--this was probably eight years ago?--a lot of us got impatient. A couple users here started a separate forum, StopAga. They thought if 1.5 mm was good, 3.0 mm would be better. If mild erythema was good, full on geysers of blood would be better--one dude posted after-rolling pics looking like a scene from an Eli Roth movie. Posters added pge2, a .5 mm roller on off days, and all sorts of nonsense to accelerate the process. In short, we did stupid sh*t.
A few of the success stories in this thread involve guys who stuck to the original protocol for six months or a year before noticing any improvement. This, obviously, is the smart, grown-up way of doing things.
