I did look at this previously but thought it wouldn't be fair on The Top 4.
There is less chance of them being overtaken by sticking to the same format whereas someone could technically gain 20 points in one week. I know that is hardly unlikely to happen but I feel it will skew the comp having completed 5/6ths of the comp.
We have another fortnight to the 19th-22nd Friday-monday round of matches to see if The Championship will restart so no rush for a decision before then.
