Thanks for the feedback, I hope you (and everyone else making the transition) will find the spreadsheet useful. I can't take the credit however, the author's email address is at the bottom of the spreadsheet in the notes area - I'm sure he'd be thrilled to have some recognition for his efforts.
However, he did OK us making changes so we can manage the copy available for download on the site.
As for Helo time. I'm not sure what to tell you, I know that there are some airlines that will allow you to count it by they few and far between.
All the best and Good Luck!
