I assume those fuel numbers are with the new airfoil. You should get less fuel with the old one.
I noticed an interesting statement in that section on your web site; "At this rate, I'll certainly be flying next year (1999). ". I have been sayint three months for the last year. Now I am finally realistically saying three weeks.
