Partial Keg, partial bottle question

[creole_hops]

I will be using the 5.7 liter Miller Keg for the first time. I plan on keging 1 gallon of my 5 gallon batch and wanted advise on how I should adjust my corn sugar for the remaining 4 gallons. I am currently using .75 cups for the entire 5 gal batch. It seems to me that .5 cups would be a bit drastic.

Any advice would be greatly appreciated.

Assuming your beer is around 65F, you'll need approx. 3.7oz. of corn sugar to hit 2.5 volumes.
