What formulae does BeerSmith use to calculate % alcohol?  There are many formulae around, but what does the program use?

Its a little complicated...

 oe = Plato_start_gravity
 ae = Plato_end_gravity

 q = .22 + .001 * oe
 re = (q * oe + ae)/(1+q)
 abw = (oe-re)/(2.0665 - .010665 * oe)

Its an intermediate term used basically to do a curve fit on the terms.  It does not really mean anything physically...
