No, he's not. Let's look at it with an example. Let's look at a 500 graft HST and let's assume 2 hairs/graft (that last doesn't matter but it's just for the example).
So, let's say all grafts grow in recipient. That's 1000 hairs in recipient. Let's look at donor. with 500 graft we'll see 1000 extraction sites. In these extraction sites we see that 65% grows back, so we see 1300 hairs growing back there. In those 1000 extraction sites once were 2000 hairs. So we've lost 700 hairs in donor to get 1000 in recipient. That's effectively of 1000 hairs 300 growing back, which is effectively 30% regrowth, unlike the 15% I mentioned earlier. So yes that's a bit better. But still nowhere the 85% HASCI promised us.
But keep in mind, this examples assumes ALL grafts grow in recipient !! Which most likely is not true, so the real number will be below 30% regrowth.
