Yes. But the biggest thing people forget is that methanol has the largest coefficient of expansion of all of the components. If you mix say 20% nitro by volume at 70 degrees, then it becomes less on a hot day, say 18% by volume. Good idea to keep this in mind if mixing on a hot or extra cold day. I think VP and some racing sites have charts to make this adjustment. IMO its not a big factor to me, just subtract a little nitro on a hot day, or live with it. Could be a factor if you are a pylon racer though.
