I may be setting the math up wrong,
but 1gal of 30/22 would be 48% methanol,
meaning a 1 + 3 mix would be 7.5%nitro, 5.5%oil, 12%methanol, and 75% gasoline

the GGL 1+2 mix using 10/10 means they are cutting 80% Methanol down to 27%.
This is the problem with trying to use high oil glow, as we dilute the Oil% with gas we also dilute the Methanol%

That is why I bought methanol, to turn local 20/20glow into 10/10glow
by adding meth to the glow before any GGL considerations
1g Meth($6) + 1g 20/20Glow($20) , + 4g Gasoline($10) = 6g GGL ($35)

... in hindsight, I should have just paid for the case of 10/10 & hazmat [&:]
