Arrow Speed
Many archers want to know the reasons for more or less speed.
We have sampled some data out of our testings. The items are guidelines which may vary in value individually.
Man sieht, in der Addition kann schon einiges zusammen kommen. Dabei ist es nicht immer von Vorteil, sich nur auf Geschwindigkeit zu konzentrieren. So ist zum Beispiel ein schwerer Pfeil weniger anfällig gegen Störfaktoren. Das optimale individuelle Setup sollte daher immer dem Einsatzbereich angepasst sein.
As you can see, we can harvest some speed. But speed should not be the ultimate goal. Better a slow X than a fast M. A heavier arrow is much less susceptible to outer influences. The optimal individual setup should be fit the individual field of use.
We wich you success with your tuning, your team at OK-Archery.
Factors of influence
Base for speed-measurements are the ATA specifications:
30" drawlenth by 70 lb drawweigth using a 350 grain arrow.
- every inch decreasing drawlength costs 10 fps
- decreasing draweight per 5# costs 10 fps
- 3 Grain over ATA weight-tolerance of 5 Grain per Pound costs 1 fps
- each 3 Grain more on string costs 1 fps
- every inch more in axle to axle costs 2 fps
- a weak shaft - same weight as the shaft with matching spine - costs 5 fps
