Calculation looks right. I've only tried 0.5% citric before, let me know how the 2% goes.

Many people use citric acid in the 2% range. There aren't any "here be dragons" problems to worry about. I think Carolyn (cmzaha) has used it at 3%, but if I recall correctly she says it can crystallize out on the surface of the soap at that dosage. But anything less than that is fine.

At 0.5% the sodium citrate is protecting your soap against rancidity (DOS, dreaded orange spots) caused by metal ions, but that probably isn't enough to prevent soap scum unless your water is very very soft. A dose of 2% to 3% will be more effective against soap scum as well as rancidity.
