I score every race a 10 (with one notable exception) because I truly love F1, I am happy to watch a scrap for twelfth if the leader is not in sight and sometimes watching a driver eke out a lead or gradually close a gap to the car in front just by looking at lap times is sufficient.
I am not being asked to compare different races, just to score each one. I don't recall the internet existing while Senna and Prost were battling but I was able to watch them on television and at the circuit, did every race they drove warrant a 10 score? Yes. Was every race they drove the same as all the others? No.
This is a light-hearted series of threads to which I am happy to contribute, if you'd prefer that I didn't then just tell me.
I am not claiming to be the arbiter of quality in F1 and I suggest that very few are. Are you, rufus_mcdufus
