Any thought on the minimum distance between jib tack and spin tack to avoid interference with the slot between the two?

I know we left the jib up on F18 (what is the distance between the two?), and wonder if the same could work with a larger F24 (measuring the gap shortly).

I'm guessing in my case the spin tack is too close to the jib tack to leave the jib up. I think the distance between the two tacks/luffs is less than 72 inches.
