People want their 99 capes faster ,so they could move on next skill or get an achivement. For example: you could mine runite ore from 85-99,and you would need 78207 ores.You would make 1,407,726,000gp.But it would take you 2793 hours.If you powermined granite it would take only 177 hours.Simply the most profitable ways take just too long people to do them, no one would enjoy mining runite 116 days 24/7, and if you play only 4 hours per day it would take 696 days. This isn't the case in most of the skills , but some people still prefer the faster way as they don't have much time in their hands.Some people have better ways to get money so training skill with normal training would actually hurt more their gp/h ration , so basically they powertrain to get faster cash.

Exp between 63-85: 368,599-3,258,594= 2889995 exp. 2889995/50=57799,9 coal ores. You can mine around 250 coal per hour on average.So it would take 231 hours for 85 mining.You make 10,288,382gp 2889995/65=44461 gold ores You can mine around 180 gold per hour on average.So it would take 247 hours for 85 mining. You make 23,608,791gp 2889995/37,5=77067 iron ores You can powermine 900 iron per hour on average.So it would take 85,6 hours for 85 mining. You make 0 gp. However you save time compared to coal and gold.Coal 145,6h.Gold 161,4h. In the time you save you could mine rune ore. You can mine 28 rune ore per hour on average. In 145,4h you could mine 4071 rune ore, and in 161,4h you could mine 4519 rune ore. Rune ore is selling at 18k ea.4071x18,000=73,278,000gp 4519x18,000=81,342,000gp Yeah powermining is really an epic fail, you make 63m more compared to coal in the same time and 58m compared to gold. Powermining granite is around 55k exp per hour so it would be your best bet , and it would take only 52,5 hours. I highly advice to powermine as it saves you money and time.
