Try searching the manufacturers websites for the aircraft specifications for likes of Beechcraft and checking over their application of NBAA IFR reserves, I think you'll find 100nm alternate distance is commonly used. But the definition I have is
NBAA IFR Fuel Reserves = Fuel for go-around at destination airport + climb to 5000 ft. and hold for 5 minutes + fly to and land at alternate airport 200 NMi. away + fuel to hold at 5000 ft. for 30 minutes.
