Re: 41 hours of latency sounds bad...
When I was a student, those taking classes were privileged to be able to use the 20 minute turnaround service (for short stacks) from 7 to 10 PM. Wow! Wheeeeeee! Sadly, I think that incomparable (at the time) speed did lend itself to "shoot from the hip" style, as one tried to fit in one more cycle of debug, submit, swear, repeat into those last few precious minutes before 10PM (22:00).
