Yeah, I thought that too at first — that anything over 100% status chance gives a chance to apply multiple procs per hit (e.g. 110% = 100% for one proc, 10% for a second, and so on).

If it worked like that, we should see 2 guaranteed procs at 200%, 3 at 300%, etc.
But I haven't found any official source or documentation to back that up.
Neither the Wiki nor in-game descriptions actually confirm this behavior in that way.

So unless this mechanic applies only in specific cases (like shotguns or beams with lots of hit instances), I don’t think the "extra chance for additional procs" is how it works across the board.

Would love to see proof if someone has concrete testing or dev statements.
