Not true. Look at Bisanga,Freitas Eugenix they all go high up in the donor area.
Look at Zoomster & Gatsby they took from high in there donor
12,138 Grafts (hairtransplantation.bg) great example not much different from Gatsby except zarev gets 12k from scalp.
Its way ahead of anyone else that is a bad donor & small as well
Freitas Extraction
Bisanga extraction
Zoomster
all no different to Zarev arguably they rest go closer to the lateral humps
