I think we're on the same page. All I was trying to point out was power is more a function of Nitro to Methanol ratio than burnables to oil. Like XJet, (He runs low oil percentages in his mixes) I have dropped the oil percentage to extremely low levels and found small amounts of power increase. That increase is nowhere near what I find when switching from 10% Nitro to 30% Nitro with the oil percentage remaining the same. As you said, mixing by volume as opposed to weight is not the same. It's like comparing apples to oranges.
