I vaguely recall benchmarking the print time of several Print Trains in the early 70s, and my memory of specifics was weak, but I know I identified three or four specific IDs that were 2 to 3 times longer and I'm pretty sure they all had mixed case, or so I think I was told. We went back to the users of those trains and either suggested changes or scheduled their large prints for those print trains during slack print times.
1403 print trains comprised 80 slugs of three characters each. The fast print sets had six repetitions of the upper case letters and digits, with a sprinkling of special characters. I've never worked with AN or HN, because our service bureau had PL/I customers, and the PN train was the first to support the not sign and nationals; IIRC it had four alphameric sets. SN and TN had fewer repeats, so I guess the worst case would be a ratio of 3 to 1?
