String test was absolutely exact on both my mares - believe it or not. Both were very small for their age (I got them as yearlings), so I wasn't sure they going to make it "horse size", but string gave 14'3 on one and 15'2 on other. Now at 7 yo one is 14'3 straight, other between 15'1 and 15'2.
But I've read it doesn't work for everyone. :)
