Go back through the fuse threads and you’ll see that this argument has already been shot down.
Really!! think about it. Your comparing your new "boutique" $$$ fuse to an old $2 original one that’s seen many turn on cycles from when the unit was new, and is carbon’ed up and bent out of shape as in the pics.
(left is new, right is after many turn on cycles)

You have no argument, all you have is " expectation bias".
