Eh, okay, I corrected the mention of that term in the entries (though I wonder why no one told me until now; I must have written that dozens of times, just in my time on RPG), and the placements you came up with sound like they would work.
And yeah, the degradation of ones with the disorder is a result of constantly going slightly below full capacity to avoid going over it, which bears the same results as draining oneself much more on rarer occasions. (It reminds me of a novel by Dean R. Koontz, in which the main character has xeroderma pigmentosum, which is a condition that - at worst - renders the body incapable of repairing the damage to DNA by ultraviolet light. The main character basically has to take great measures just to avoid bright artificial light and, obviously, sunlight, and lives mainly in star-, moon- or candlelit darkness. The consequences of neglecting to be cautious about light, the character described, were accumulative in the sense that several seconds of bright artificial light every day of a month was as dangerous to him as spending a suicidal minute in direct sunlight. Anyway, it's the same kind of principle with this: the effect is accumulative.)
