magnetic deviation azimuth

I lived in Orlando, FL, my Azimuth calculation is 210.4. Does that mean my my magnetic deviation would be 215.4 according to the True North chart?

215.4 would be your compass heading. Your deviation is the difference.

EDIT: On reading the other thread where you're asking a similar question, I'm not 100% sure you were asking what I thought you were. Ie, I was answering assuming that you had looked up your azimuth/elevation to a specific satellite (ie what you'd use for a fixed dish). Ie if your azimuth was 210 {true}, then your compass heading to that sat would be 215.4 {magnetic}. Actually I used a program I downloaded from USNO, and the deviation for Orlando was more like 5.25, but 5 is close enough.
