Ralph, I disagree with your mix, it is close..
"For instance take 9 ounces of 15/15 and add 3 ounces of methonal will make 12 ounces of 10/10.
Then add that 12 ounces to 24 ounces of gas and you will have 36 ounces of gas/glow fuel "
composition 66.7% gas 25.8% meth 3.75% oil 3.75%
The differencce is that you dilution with meth yeilds 11.25% oil and nitro not 10%. An example using 10oz adding 5oz would have been perfect yeilding 15 oz to added to 30 oz of gasoline for a 45 oz total.
I think this will give the desired mix. [i

To Mix a gallon of this stuff : 28.1 oz glow, 15.6oz methonal, 84.3 oz gasoline.
If I had not tinkered with this some time ago and made a spreadsheet calculator format, I would not have bothered with the post. The percent of methonal difference is probably not that important.
More than most care to know.
