Not sure about those numbers. I've got the same Brewer's Best kit in secondary right now, so I'll be bottling it soon. Beer smith and every other resource I've found say it should be between 4.1 and 4.4 oz of priming sugar for a 5 - 5.2 gal batch to get to the 2.3-2.4 vols of CO2 that BJCP style guidelines and other books recommend.
Using only 3oz for a 5 gal bottling batch will result in only 1.9 vols.
Of course, everything's to taste, but I'm trying to achieve something that my friends and I will recognize based on other popular sweet stouts.
