My view then lol:
I like this idea, but can only see it being used to certain extent, for example there are many good drivers now easly capable of making the top heat, but however say Kev Lee turns up again, he would obviously have a very high grade, but does this mean say one of the top usuals should be knocked down a heat to make space?
However i do agree there are still some issues with capable drivers being very low heats, take Ross for example, good driver and easly capable of making the top 5 but he has a bad few weeks due to tiny little problems, he is now stuck in a lower heats where is he is 2/3 secs a lap quicker it makes it difficult for him to get out these lower heats due consistantly lapping slower cars. This not only makes it frustrating for Ross but also to the lower drivers due to the pressure of consistantly trying to let this faster car lap without taking it out

.
As i remember when i started it was hard enough to keep the car on its wheels within that 1/2m gap between the ropes, without trying to get out the way of another car
