He's correct - the best way is to follow the instructions. Sight in at 20 yds and then work your way back to 60. I've had the best success when I spend a little extra time at 60 to get things dialed in to the best of my ability. Once you do that figure out what tape you need, slap it on your sight and you're done.
It won't work for your sight but this is a pretty easy way to sight in a multi pin setup. https://play.google.com/store/apps/details?id=com.NexsysSoftwareSystems.sighttune
When I installed my HHA, I nocked an arrow with my old sight on. then I measured from the arrow(not drawn) to my 20 yard pin. I installed the HHA and set the pin to the same measurement as my old sight. I was within 2" on my 1st shot. Then adjust from there.
