[Rules] Let's extend the Belgian Grand Prix to 400km

[NaBUru38]

F1 should have just one race per weekend. If there are two with equal length, there wouldn't be one true winner per weekend, and I wouldn't tolerate that. If there was a sprint+feature format, the longer should be put in the end to make sure that everyone understands that its winner is the weekend winner. But the sprint race should be put in the end too, because if it was held first drivers would drive conservatively to make it to the feature race. That's a contradiction, therefore I'm against multiple races in a weekend. That's for F1 - I accept that championships based on the concept of fun (Superleague, Top Race, IROC) and development races have multiple races per weekend.

I like BootsOntheSide's criteria to determine the number of laps. I mean the "number of times the pole lap would go into X minutes", but with different minutes depending on the circuit. Currently, races on faster tracks always last less time than races on slower tracks, and I dislike that. I like that Monza lasts 1:20 and Monaco 1:45 in dry conditions, but I would also like a longer race in a fast track (Spa, 1:40) and a shorter race on a slower track (Hungaroring!, 1:20)
