0D mask, good pcm .
7.69 vs 7.71 is 0.02 which is less than 0.003% error. Not too shabby in my opinion. Also, there is error caused by other variables to just get it close and call it good.
There is sometimes a resolution limit in the code that will force you to use a value not "exact." Like for example; 8-bit values for SA are raw * 0.351567 . So if your base timing is 8 degrees you only have 7.73 or 8.08, obviously 8.08 is closer to what you want, so use it and move on. Everything is compromise, don't get hung up on decimal places.
