Thanks, I have been using this http://www.tastybrew.com/calculators/
Everything adds up correctly.....
Desired C02 = 2.5
Gallons of beer = 5 gal
Beer Temp = 68 degrees
Results = 4.4 oz of corn sugar.....I used 5 oz so if anything the beer should be properly primed. I used the calculator you linked to and the one I normally use and had the same results. My beer probably just needs another week or 2 because the temp is slightly below 70 degrees.
This wait is really disappointing. Right now everything is telling me to spend some of my tax return on a kegging system
