Just read Doncaster lost 1 full point, as they have a gantry 40cm too small.

Oldham moved to a bigger stadium quadrupled their attendances but lost points under the 'utilisation of a stadium criteria,'

Whether we're a Grade-A or Grade-B club, we are still a Super League club, which means that our future and the direction of travel remains in our own hands, no-one else's.

The key is to start behaving like a grown-up sporting organization, something which has been sadly absent for far too long unfortunately. The prime objective of any sporting club is on-field performance, winning matches basically! All of our other faults (as highlighted in this, admittedly flawed, system) will recede if we once more start winning a game more than once every Sheffield flood!!

It won't be easy, we are having to come from a long way back, and my suspicion is that 2025 will still be a difficult year to sit through, but we have to start the road back from somewhere.
We are probably now about as low as we can seriously afford to drop, barring a fall into complete oblivion, and so I would think our grading performance can only go back in an upwards direction again, but it really is linked to our on-field performance. I hope J. Cartwright realises the weight which will fall on his shoulders the moment his feet touch Hull terra-firma!!

Have wakefield scored more than us for performance despite finishing below us for each of the years of the measure? Clearly someone knowledgeable has come up with the criteria

I wonder if they failed on girth or length.
