according to

at 38 degrees F my beer needs 12 lbs of psi to reach 2.57% carbonation

or is it at 38 degrees F my beer needs 2.57 psi to reach my estimated carbonation level in 12 days

I'm quite confused in this chart I have only "burst" carbed before, and I'm looking on getting a specific carbonation level for my competition brew.

a couple questions I have

how long do i leave my beer carbonating?
are the numbers at the top of the table from 1-30 my psi?
what do the numbers in the colors representing?

At 38 degrees, 12 psi once you reach equilibrium (2-3 weeks without any agitation) you'll have 2.57 volumes of CO2 in the beer. Everything on the chart is labelled pretty well?

The colors are just to give you an approximate carbonation range (see the bottom) and the top is labelled PSI. If you're using the "set and forget" method you just want to leave it at that pressure and not change it. Should be mostly carbonated after 2 weeks.
