Oh yeah. That Fury was 43rd attempt that day. In general Rage and Fury are a nightmare because you are basically waiting for planets to align - crits on heavy hitters, set procs, even offhand hits all factor into it.
Actually I was using TD after every Cull until yesterday, only changed that because of someone who is trying to learn Virulence and the guide she linked me - in fact that parse is the very first one after I switched it. Haven't really done any proper math on it yet, though, for me it's mostly muscle memory at this point.
