Crap, I don't even want to know what that feels like, Im at like 20 in each leg/foot due to 2 fragmented discs and there are days I can't feel my toes from the midfoot forward. Makes taking steps fun, especially since I work in the basement. Ive had 3 good falls in the last 6 yrs, 1 resulted in a broken wrist and surgery. Restless leg and sleep are bad enough at 20.
Yeah, VA math seems weird, but its similar to what loss actuaries use, calculating from whats 'left' after the loss, rather than just adding. That last 10-20 percent really sucks.
