Wow - ok. On the basis that he needs to have completed the sequence beforehand and on the basis that any figure needs to be understood and repeatable (otherwise how does the pilot or observer know what is to be flown - and flown safely) it has to be something. I called it a 1/4 clover, what do you call it? We could say that a 1/4 clover is a figure with vertical and rolling component - especially when you enter on the A axis and exit on the B axis...
Edited to add: I think when you look at the CAP403 definition of "standard" aerobatic figures it would appear that you can not fly a 1/4 clover within that categorisation because turns have to be in "normal flight" and loops have to be circular with normal entry and exit.
