…Good point…but why? I am not assuming it to be truly continuous, but do you think it is a natural discrete event? Or are we stimulating it correctly (nutrition, sleep, whatever) and then failing somehow to continue?

Well, let’s leave apart weigth training for a while; I think real PE gains are discrete, yes. What one see after a good PE session is a temporary reponse - fluids build up, elastic elongation etc., that could hint a good work; it could be also be misinterpreted.
Real gains are coming from healing; I think an appreciable amount of damage is required to see gains, so an appreciable amount of recovery (so, delay in time). I suspect there is kinda a ‘point of accumulation’ of damage, above the one gains start. If this point is not reached, no permanent gains are achieved.
I suppose also there is a range of damage that cause the kind of gains we are interested in: surpassed that, no gains, but stalling/strengthening; surpassed the stalling damage, injury.
Basically, as often in my posts, a bunch of hypothesis, based on personal experience and anecdotes. :)
