On mainnet now is a limit by contract 10% - https://arbiscan.io/address/0x7aFC144a0c3C62e24d8f9c592feF8F65ce631C59#readContract#F1.
But in code still 100% is the maximum - https://github.com/carv-protocol/verifier/blob/main/cmd/verifier/main.go#L135-L145
So when you start verifier you get error from gaslessservice but not by verifier
