Okay, it's some very experimental math and we will know for sure tomorrow, but I was curious so I went ahead and tried to estimate male Viera minimal height.
In benchmark the feault value is 58/100 and is 180.5. 100/100 is 186.5 (as shown somewhere in this very thread).
What I did is I basically counted what would be the height value at 58/100 for other races, checked how it scales in character creator to know if it matches (it does), and from there started picking value for minimal height that would give 180.5 at 58% in result. The closest value ended up being 172.2cm. 172.3 works as well with 180.54 as 58% value. (the basic formula was minHeight + range*0.58). There were some other values peakable in creator, like 173cm for 6/100, which I also experimented with in formula, and it seems to scale fairly accurately.
Again, this is highly experimental and we will find out how accurate it is tomorrow. x)
