As long as the base spark constant in your bin is set so that it matches what's physically set on your distributor, you don't have to add or subtract anything.
Edit: Don't forget that there may be other corrections applied, for coolant temp, PE spark, etc. in addition to the main spark table.

There isn't 1 table that reflects the engines actual timing and depending on the software you're using it might be more intuitive. I have all my xdf files setup so that the table bias is included in what is displayed. This helps with the correction tables. The main SA table also might have a bias, again, it depends on the software. The initial SA or base SA value should match the actual engine's base timing. Do that and the main tables will then be the basis.
