As for a formula I think maybe you meant the formula referenced in #2? Again my math skills and understand of how the math works is seriously lacking especially when trying to even begin to write the code for a PIC.

Hi, Ed

you're right was @Post #2 ...
If I'm right ... you're begging for the full PBP calculation ...

Sorry, but I won't be able to take care of it before next year ... as I'm the WHOLE family cook for the moment.

Please, Understand it needs ... a little amount of time, as a retrieve table has to be calculated , and you need the full working subroutine ...

BTW ... knowing which processor you use could be necessary ...
