Find the viability of each and add them. I got 75% for one and 27% for the other so you can assume 1 vial at 102% (production date is 4 months prior to date stamped on vial). Uncheck the "Calculate Viability from Date" and type in 102%. Move the growth factor slider until the "#Vials or packs needed with starter" shows 1. So for example, for a 5 gallon 1.054 lager starter on a stirplate, I get a 3 liter starter for your 2 vials.
