Ron, I busted a gut and more , 1200 hours for 20 years.
It wasn't just the number of hours, it was the way they were earned! My wife pioneered for years in the 1960's and 70's, there was no standing around with a witness trolley for hours on end drinking Costa and talking to ones mates. There was no phone witnessing, letter writing. It was all D2D, Back Calls and Studies. Literature had to be paid for so it was never dumped in the local washeteria or doctor's waiting rooms. She always aimed for about 115 hours to allow for holidays, assemblies, illness etc. The annual hour requirement had to be met to continue as a pioneer.
