16 levels isn't an enormous amount of exp under those levels in the 70s. There is a need for 77 mining to get concentrated coal Old School RuneScape Gold, and you should put it in a bank rather than powermine. Concentrated gold is level. If he's lucky enough to have an option to choose a dragon the odds are that it will be a close race, if I'm not mistaken. The rates for exps shouldn't be significantly different, but if you have a team that is strong I'm betting you'll get the cut first.

Yes , it's a lot of xp because dung also isn't fast for lvls lower than 70. Powermining, in addition, is a lot faster. This is why I said he has no chance if he is operating at level 70 is less than 1 million exp, you have to accumulate 13 million exp in order to attain 99. The first 1m (even in the initial 6m) doesn't make a single bit of difference, at 80 mining , the miner is at the point of reaching his optimal performance rate, which is around 100k/hour.

The higher he levels gets faster and faster to the point that at 70 he has already surpassed the miners top speed(provided there is a strong team) I'm not sure why you guys cant see it's a one horse race. The winner should choose a skill that is slower for fairness.

However, if we are fair We picked these talents since we both love doing these activities. To clear somethings up that we're both members. my brother does not own the dragon pickaxe. A dragon pick for mining can be compared to a good team to dung Buy RS Gold. Without it, it's an option, but much more challenging. The only way to lose is if you go solo and he picks a d pick.
