Yes - an old thread indeed!
Firstly I agree there is no obvious link other than for the most part a taller woman will generally have most things in the same proportion (longer arms, legs torso etc) even the small negative correlation still means that taller woman are likely to have longer arms legs, torsos, vaginal canals etc - it just means that if theres a slight neg correlation then taller women will have slightly shorter lengths given there much taller heights (if you follow!)
My own PERSONAL experience (about 45 women of all heights, but mostly at least 5ft7/8 is that Ive run into fewer problems bottoming out with taller women (I'm only 7x5.4) - perhaps thats why its my preference LOL
That said there have been petite women who had no problems and a 6ft1 woman who said I was the biggest she'd had (and she'd only had about 10 guys previously)
But I am biased. I prefer taller women, and Ive simply had less issues with bottoming out or the "ouch factor"
Again just my own experiences. YMMV, as they say.
