I still think the run times should be the same not the number of laps, that's the great leveller.  I'm looking forward to driving the cars when they arrive but only 30 seconds is still going to feel like a rush.

With one minute runs, 43 cars is only one hour per Rally stage.

What do the other hosts think?

The problem is that the actual run time is often only part of the picture, as many of us will testify. Preparation and replacing cars that easily come off the track, each hosts situation can also make a theoretical 2 hours into 3+ hours.
But I am happy to give an advisory recommendation.
