I think to back up the hunch you'd need to poll some people, see if their akrasia comes from being weak on some points rather than others - if that's the case, and they're not consistently the same points, then probably it does work that way. I personally feel like I'm bad with respect to all the modules listed.
Yes, that's what I was trying to do with the parent comment. I used myself as a reference for these points, as well as drawing on various anecdotes I've heard about other people.
E.g. I'm high on "negative willpower", high on perseverance against physical discomfort (tiredness, hunger, pain), low on perseverance against boredom, frustration, and the feeling of being stuck.
I'm very low on #1, and also have low affinity for, say, math, and hence I never put in the hours for learning it well, but I've heard of people who are also low on #1 but happen...
