Hey guys, what are you all using for your carbonation priming calculations? We're having issues w/ carbonation, and it's gotten frustrating. It's really inconsistent, some of our beers are perfect, and some are quite undercarbed (a citrus lager and a brown ale), and we just had a stout that is slightly overcarbed.
I've been using Brewer's Friend's online calculator here:

It takes temperature into consideration, which I thought would yield us even more precise priming, but it has not. The lager that was undercarbed was bottled at ~40 degrees (post lagering), so the calculator said to use much less priming sugar. Unfortunately that did not create enough carbonation.
I use a scale to measure out the priming sugar to the 10th of an ounce. We're also mixing in the sugar water thoroughly, so I'm not sure why we're having issues. Anyone have a more tried and true calculator or method? This seems so rudimentary I'm almost embarrassed to ask.
