Ooer...apologies, I am obviously seriously out of date...

However, the BRCA rules state that qualifying can be RBR or FTD at the Race Directors discretion..!
I bet I am not the only one who finds RBR confusing whereas FTD is obvious..
To help myself ,and others understand RBR ...here is an extract from the BRCA
The Round by Round qualifying method awards points for each competitor’s position in each qualifying round individually. Highest qualifying position in each Round will score zero (0) points, second place will score two (2) points, third place three (3) points and so on. (Regional events can amend this points system subject to software compatibility). Weather/external circumstances may prevent all scheduled qualifying rounds being completed, therefore points from each driver’s best qualifying rounds are added together to determine a final qualifying position as follows :-
This suggests that if ,say, there are 40 drivers at a meeting, the fastest driver each round scores 0 points and the slowest driver scores 40 points..?
That I understand...

However I am fairly sure that we are not doing that, so must be applying the "amendment subject to software compatibility" .....that's what I don't understand...!
Probably I am wrong again...
