I made an Excell sheet that explained my times and how I converted them.
Somthing simple, easy to read (1 Page). So there's no doubt on how you got to your conversion time (i.e. .3 per sortie, .2 per sortie, or .3 per hour).
That was in addition to my AFORMS product signed by the guy/gal in charge of giving you the products

Good Luck!
