Really !!!!!

Arrow speed (downrange): 65.77 m/s -- 215.78 fps 

Time to reach 18 meters: 0.26 sec 
Time to reach 30 meters: 0.45 sec 

I calculated the following sight marks (relative to 18.0 m sightmark): 
for 18 meters, move sight pin 0.00 cm up (time in flight = 0.26 sec) 
for 30 meters, move sight pin 1.35 cm down (time in flight = 0.45 sec) 
for 50 meters, move sight pin 3.61 cm down (time in flight = 0.75 sec) 
for 70 meters, move sight pin 5.89 cm down (time in flight = 1.06 sec) 
for 90 meters, move sight pin 8.19 cm down (time in flight = 1.36 sec)
