My buddy and I will be brewing our version of the original recipe on Friday. Can't wait to see how it turns out! Yeast starter is (hopefully) churning away at home at this very moment.
We got an early start so we should be able to get some good long bottle conditioning in before Thanksgiving rolls around.

I know you asked this almost a year ago, but if you still find yourself in need try the below equation.
(And if someone sees a mistake please correct me!)
abv = %ABV before rum addition (i.e. 9.2)
pr = Rum proof (i.e. 80)
R_vol = Volume of rum being added in fluid ounces (i.e. 12)
Tot_vol = Total volume of beer (at the time of rum addition
) in gallons (i.e. 4.5)
New ABV = 100*[ (0.01*abv) + [(0.005*pr*R_vol)/(Tot_vol*128)] ]
