It's not uncommon for your sight tape to not match your fps. I always make a mark at 30 yds and 80 yds. Then choose a sight tape that matches. I measure the distance between both marks with calipers. There is also some sight tape programs out there like archers advantage to get really precise.
I'm a Montana Black Gold sights fan. I use the 5 pin sliders. I don't have to dial until past 60 yds. Top pin is .019 and the rest are .010. Pin colors are G,G,R,G,G. I can't see yellow pins.
