I posted this last week, I spoke to a couple of club managers at a lunch recently, they weren't overly happy with the approach from the QRU about this trial.
Sounds like at least three clubs simply wouldn't be doing the calculations needed to ensure proper player discounts are applied. I'm not across the workings of it at all, so can't comment if the QRU have been slack or if these clubs are being a bit precious, but it sounded like they wanted some additional resources provided by the QRU to get it all running.
I might be overly simplifying the task, but it sounds like it would only be a bulk calculation once a year and then let the figures roll until the next season.
