Hi Bill,
If my math is correct you are looking at 30 cc = 1.014 oz. of fuel. If you are looking for a target time you could start with dividing the current records by 4 to get a good est. ?
This seems to take all the flying endurance and logistics out of the effort and makes it 99.99% of an engine and min drag plane issue.
I like the old 4 oz rule myself, but I do understand the many good reasons to go to the smaller fuel amount.
The Senior record looks like a piece of cake to set. I hope you guys tackle the open and junior records too. It would be fun to see a ringmaster hold these records!

Good Luck,
