UPWA,
Interesting article but I believe it was not prepared carefully.
If you run the numbers yourself, you will come with a utilization of over 15hrs/day!!! These poor guys mistook the 529 hours/wk for minutes
So, I don't know if it was a planted article for purposes only locally involved ones would know (definitely not me), but if not, then their editor should be more careful with publishing their work.
I hope they don't base their business decisions on similar studies
