It's all nonsense.
They are regrading riders like Tai to a 9 (or 8 it now appears), allowing some who have improved massively since 2016 to come back on an old average (Woryna), and then giving Clegg a 2 point average from his 4 meetings for Wolves which normally wouldn't qualify you for a new average.
Depends who is asking as to who gets an average to suit. The governing body haven't made one fair assessment yet on averages for 2018.
So some will get an advantage next year and some will be denied. All thanks to the pathetic efforts of our governing body to muck up the averages yet again.
