When you look across a number of leagues you can see that a number of promotions and relegation's on games played v points obtained make quite logical options.
The problem I think will come where there is no account of the remaining fixtures other than the number to be played, as opposed against their probable outcome?
I am fairly sure that some teams would have been looking at a game against YM home or away was likely to be 4 or 5 points in the bag. Yet a number of teams have already benefited from fixtures against YM this season. They may also benefit from a percentage of points awarded by the formula used by the RFU, when they possibly wouldn't have got any thing from the game.
I am sure that the RFU will do their best to come up with as an equitable solution as possible. Unfortunately as all things in life some will benefit more than others!
That said it is an amateur sport that is to be enjoyed by all participating in it! I am sure that both YM and possibly WH in this league and certainly Ilkley from the league above will happily accept relegation, there can be no fun in travelling sometimes significant distances to get spanked and not be competative?
