ftd you only have to have 1 good run out of 4
rbr you still only need 2 good runs out of 4

its hardly a massive difference but does help equalise the inconsistencies of a days racing, track moving weather changes surface changes etc.
it is ultimately the fairest way to score a meeting.
it teaches us to race conservatively rewarding consistency, which in turn teaches us to drive faster without crashing. all ftd encourages is balls out runs where if you crash it doesn't matter. as you can try again next run, but this also encourages people trying to drive faster than their skill, this can lead to them crashing and either wrecking the track or binning someone else off the track.

these are the reasons the brca off road section and the oople series use rbr
