"Maybe a week of mileage higher than your LSAT score?"
Much harder to achieve, unless you're a dumb, with a massive capacity for training. LSAT range is 120-180, median 150. Even a 140 is really, really unimpressive/takes some doing. It'd be possible, but it's a pretty small overlap there.
Not to mention that the LSAT is eminently teachable, and that if anyone were sufficiently dedicated to run three-figure weekly mileage, I could tutor them to at least a 155, probably a 160.
