Your formula of 25 gal WVO 3lbs KOH and 5gal of Methanol is a very good formula that I believe Fabman came up with and I have been using for a long time. Calculation of KOH at a minimum of 8grams per liter comes to 757 grams of KOH. 3 lbs of KOH converted to grams comes to 1360.8 grams, about 42% more than the 8 gram per litre minimum. With this recipe Titration is basically a waste of time if the WVO you use always comes from the same supplier. If you titrate, you can calculate the exact amount of KOH needed which will be alot less than 3 lbs. As I stated before, for the little extra cost of KOH, it is not worth the hassle for me to titrate.
