You see no difference between 20 vs. 25 amps and 20 vs. 100?

I didn't say any difference was unacceptable, but a significant difference for 20/25 should not be accepted.

If the danger gets gradually worse for every 5 amps on the fuse, that's fine. Then the excess danger at 25 or 30 amps is only a tiny fraction of the excess danger at 100 amps. Good work.

If the danger has a sudden sharp increase at a certain amperage, then that amperage threshold needs to be further away than a mere 20/25 difference. Or even 20/30.
