What I've read is:

'The clubs will be re-assessed every year. Teams will stay in the top flight if they keep their Grade A status, with the best of the Grade B clubs them making up the rest of the competition.'

So for the moment we are the best rated GradeB club, and 10th place overall so 3 GradeB clubs would need to get a better score to relegate us. Obviously it's get complicated if we finish poorly again and a championship clubs bags bonus points for Cup and League wins but ultimately I don't see 3 clubs overturning us in the scores in 1 year,

As you say whoever wins the Championship/Play Off Final gets promoted as long as they are a Grade B club so conversely any club in SL that finishes bottom should be relegated grade B or A as I can't see the point of relegating a club on grade score rather than finishing bottom. It just wouldn't make sense when clubs in SL are A or B anyway and you have to be a B or higher to gain promotion like Wakefield have.

So its should be as simple as any club that wins promotion goes up (as long as they hold a B grade as minimum) and any SL club that finishes bottom is relegated (whether A or B). But in true RL fashion in the UK we have to make it far more complicated than it should or needs to be.

Same time of year again in October.

But again the league finish for one year doesn't really drastically alter things as it's a 3 year average in theory a club could finish 12th, 12th and then get a billionaire owner and sign the NSW SOO Team and finish 1st and still have an average of 8th for the scores. It has to be 2 or 3 years of sucess to nudge the scores really upwards.

not just about league places though is it. You could get another teanm sorting issues out and coming higher like we are hoping to.

Either way it's a shambles. No one in their right mind expected to see waky and cas get grade A's
