put right foot up on lip, slap to good incut sidepull, swap feet, pull over for jug.
BUT climbing up, clipping, climbing back down, then falling off onto the pre-clipped bolt but leaving it preclipped for the next attempt? No. To me that's cheating. As usual it's what matters to you, but if one of my mates was doing that i'd try to give them enough abuse about it to make it worth their while not to cheat again! If you blow the onsight do you just lower off and leave the rope in yo-yo style? Hell no
