You're welcome, and what's even better, you did it by yourself.
Now go and write it out 100 times before sunrise, or I'll come back and cut your Balls off.
edit.
I would suggest that the data you referenced is for a BE-33A, with a max range cruise in the 115 - 120 knot range, and with your example of 80 knot max range cruise, I would expect something closer to half (or even a bit more) the headwind component should be added.
However that is only a guess, I have not done the numbers.
