hand wringing isn't going to change that...for the two reasons I've explained at great length...the sooner you get out of the "Denial Stage" the sooner you'll be able to deal with it. In your business, IMO it will be a very long time before you see anything but "JetA" being used, so aside from the price fluctuations, you'll still be in the same business when you retire.
As for any data, you can search for it...I've given it to you more than once..
