Do you know the DP of each malt?

the caravienne, toasted oats, flaked barley, chocolate, and roasted are all 0

so a total of 2.75 lb of 0

let's say MO = x and Vienna = y

(2.75*0)+(4.5*x)+(2.5*y) = (4.5x + 2.5y)/9.75 = total DP. if it's over 40 you are golden. if it's close it's probably fine, just might want to mash longer.
