  The surveyed users had an accuracy of 8% doing the prediction manually in the same settings on an 5 digit pin. So scrambling seems like a good idea if you are going to use a PIN.

  Well, if the numbers were scrambled, then the user would need to look at them - so a video from the same perspective would record both the numbers and how they get entered, and it would not help in any way.
