On a track like ARM speed is hard to come by, I know the car I'm using is better on larger tracks but speed shouldn't be too much of a factor on the first section, its tight enough that it'll be hard to generate a huge gap for the most part.
Speaking of ARM, if it were me I would shorten the run by a corner or two, the entire track as a tandem run seems a bit excessive in my opinion. I think if cars courtesy rolled down the hill into the left hander and then started the run just after, with the first clip being the fast right hander before the mini straight, it would provide a much better battle section.
Most real life sections in competitions consist of only 3-4 corners/clipping points, so I think the length and complexity of the full ARM track may be overkill.
Just sharing some thoughts. đź‘Ť
Edit: It would be easier to get consistent judging as well.
