Well, depending on how you interpret scores lower than 8, I could be pretty close to a 25-point character.
Str 7
Dex 6
Con 8
Int 17
Wis 9-11
Cha ??
I have no clue how to measure my Wisdom or my Charisma. I know my senses are pretty dull, and I have to concentrate to understand what other people are saying to me. It's probably in the 9-11 range, but I have ranks in Sense Motive and probably the Iron Will feat.
Charisma? Everyone I meet remembers me. The vast majority of them like and respect me. So, probably a bit higher than average Charisma. I've had people actually comment on my "force of personality", and tell me that I have an "aura of authority", a "quiet sense of dignity" and all that. I even had one person run around telling people I was a "manipulative son of a bitch" and an "evil mastermind" that was controlling everyone I know.
All of this is incredibly flattering, but patently ridiculous.
As for the physical stuff... People think I'm stronger because I can carry more, but how are they going to notice a lowered movement rate? I've got a movement rate of 10 feet and I can't run.
The only sign of Dexterity I have is that I type at a very rapid pace. On the other hand, I have less than normal flexibility in most of my joints (except my fingers), I move slowly, I lack coordination, and I need a cane to walk. (Mostly for support, but it helps my balance a good deal, too.)
Constitution? I'm allergic to myself. I can't measure how long I can run... because I can't run. I can barely hold my breath for a full minute. I get sick every couple of months, and when I get sick, I stay sick for a long time. The only signs of an above-average Constitution I have are my tolerance for ingested substances and my pain tolerance.
I don't know. I may be more than 25 points, but I'm sure as hell not heroic.
