As the title states the purposed changes would increase the amount of headless arrows based on fletching level to speed up this process keeping the actions per hour the same.
At the moment the average player can fletching approximately 45,000 headless arrows per hour based on a 3000 actions per hour. The purposed change would see headless arrows per hour be buffed based on scaling exp using air runes as an example.
(Fletching level v headless arrows made)
Based on the 3000 actions per hour:
Level 1 = 45k /hr = 150 per action
Level 11 = 60k /hr = 200 per action
Level 22 = 75k /hr = 250 per action
Level 33 = 90k /hr = 300 per action
Level 44 = 105k /hr = 350 per action
Level 55 = 120k /hr = 400 per action
Level 66 = 135k /hr = 450 per action
Level 77 = 150k /hr = 500 per action
Level 88 = 165k /hr = 550 per action
Level 99 = 180k/ hr = 600 per action
Acknowledge that headless arrows are 1.5 exp per arrow. This would change the rates of exp per hour but I don’t see that as a major issue as this doesn’t even come close to making arrows per hour exp rates.
Also you can just buy them on the GE
