Forum:Eidetic Memory or Hyperthymesia?

I'm curious as to which condition applies more accurately for Thane (or any Drell). Eidetic memory is the ability to recall almost every detail about something studied. Hyperthymesia is absolute perfect recall of all personally experienced events. From the way Thane describes it, it seems like he has hyperthymesia, meaning that he perfectly recalls everything he experienced. I know he says Drell have perfect memories, but it seems more like an advanced form of hyperthymesia. So in addition to remembering everything he's been through, he feels them as well. I'm sure it could be eidetic, but eidetic is flawed in that the memory does fade eventually, whereas Thane's memories from years ago are perfect. I know it's nitpicking, and I'm not trying to be a jerk or anything, I just thought it would be cool to have it a little close to correct.
