Peak current can exceed the fuse rating as automotive and maxi fuses have very leniant tolerances example: a 30 amp blade fuse has +20% @ 5 second / +50% @ 1 second etc..
The fuses dont instantly blow at their rated capacity - Since each manufacturer has its own tolerances it would be very difficult to use that as an accurate gauge.
Agreed, it's not gospel, but it can put a ballpark number, and it makes for a good time when someone has a 2000 watt amp with a 10 amp fuse in it.
