That looks about right. Not sure if the tiberius adjustable riser is one degree of angle per click. The range (x) yards column would be your distance to poi, height column is the height of any overhang you're shooting thru (i.e. making sure that if you are shooting at 83.6 yards or 5 degrees that there are no branches under 7 foot above where you are aiming) and the @ range (yards) is the distance to the max height of the arch. And you might as well toss out anything past 8 degrees, if the wind doesn't blow it off target, it will be to slow to break on anything.
