Pees in the brown Koolaid
500 drivers tested the DIAD IV for over a year. They were in multiple districts.
I'm sure someone knows more about that testing than me..
I will hazard a guess that all 500 test drivers complained loudly about the location of the signature button....but the IE guy in charge of the testing ignored them because he didnt want to spend the small amount of money it would have cost to move it.
