Not the worst clear ever but the stars kind of need to align. You need good mgr luck throughout, enough Mad Strength procs to take out Salamence before its third Earthquake, not get nat crit, and at least 1 X Sp Def mpr (getting more gives you more leeway for whether you can get away with syncing before bar 3.5). I had a smidge of DR from the skill gears and it made this a lot more consistent.
