And tris, just an FYI for next time you do up a batch. This is something that I thought of doing after I made a similar mistake... although not as big as yours. lol
Set aside your brew materials before you even start cooking up your gear. For example, instead of adding each to the powder, this is what I have done.
Fill a beaker/syringe (dependant on the amount) with the exact amount of BB, then a beaker/syringe with the amount of BA, then a beaker with the excat amount of oil. Double check what you put in the beakers/syringes. Then add them to your powder.
Again, this is making things extra dificult, but think of it as you were preparing a food recipe. Same thing. You don't want to add 2 cups of salt instead of 2 cups of sugar right? Same thing applies.
Just a thought for you.
