from what ive experienced so far,runemate counts the hours a bot is being active with breaks and all. This is multiplied by how many accounts are being botted.for example I used a mine bot on two osrs accounts for 10 hours on each which used up 20 out of my 200 allotted. now to further add to that if you were to bot an account for 8 hours a day for 5 days a week you would use 40 hours. Now a month would be 160 hours.
