I'm confused as I thought there was no rate. I'd imagine anywhere from 15-25 a minute is an acceptable rate depending on the conditions, which is manageable by most experienced staff, but the confusion here stems from the rep agreeing with the DOMS figures of 20 p/m minimum.
Effectively, they have had the traffic sheet stats used against them, which I'm sure the IWT/pareto thread was regarding. My only thought is it could be a new work plan due to recent agreements?
