I think it would be very unusual to revise the field performance
I hear what you're saying, e.g. Cessna did manage to get the 560XL figures horribly wrong in places and have done nothing. But I suspect Cessna realise that Blink or maybe LEA's success in operating Mustangs could be very significant with the Phenom snapping at their heels. I'd redo the math if I was them
