Benni's 1015/461 kg is respected as THE deadlift WR among powerlifters pretty much everywhere.
With those millions of federations, non-affiliated comps etc out there you just have to count whatever people do that gets passed in those meets.
Otherwise you'll end up having a lot of huge numbers not being accepted as WR despite being totally legit.
You'd be surprised how many people in the USA who compete don't hold Benni's record as official due to who put the meet on
Katterle has a pretty bad reputation for not having accurate weights at competitions, it's still debated after all this time as nobody weighed out the bar + plates to make the weight official as happens often when there's question over legitimacy. Had he simply heeded that request from people who wanted to be sure everything was accurate (other competitors at the same event said that they were pulling PRs beyond expectation, and that the weights truthfully felt as though they may have been slightly light). I preferred how it was decades ago where ever world record lift had to be weighed out to ensure the integrity of it considering how often records claim to be broken, but either way, strong pull and I won't lose any sleep over it
