That is interesting.

I’m sure it depends on the application to some extent. I can type my pin in without looking at all, so I can cover it up while doing it. If I had to hunt and peck, it’d easier for an onlooker to observe my slower motions I think.

But if I used the same machine often enough to produce wear specific to me, this randomization would be really useful.

I use a randomized PIN pad on my phone, and I've gotten quite used to it. I can enter my PIN almost as fast as I could on an unscrambled pad; it's definitely not hunting and pecking.
