I was going back through the HARP SF book, and noticed high gravity adaptation makes mention of having a short, squatty build. Does this actually change the character's height by some amount or percentage? Among the other modifications, the character incurs a loss of presence modifier (because the guys at ICE feel short people are less pleasant, I guess?). If that's the case, what happens if you mix it with the giantism talent, which increases height by 50%? Does the presence mod go away, assuming you get back up to at least normal height for your race (a pretty safe bet, probably)?
