Rift Ball: Carnage Report, Accuracy

So my carnage report for Rift Ball in Action Sack says my Accuracy is 1,900.0. I’ve Googled everything I can think of but nothing tells me what this means.

Anyone know?

What weapons does rift ball use?

Could be the same in grifball. Since a single hammer swing can easily damage more than one enemy, hence greater accuracy. Edit: Meaning your accuracy goes past 100%
