We already have been doing this. (using the bottom of the list)
I had set the threshold for that at 6 cars. If there's 6 or less, we switch to the bottom of the list for some/most races.
The reason I don't do it at 7 or 8, is because when we get to that many people, there's more potential for confusion & hold-ups.
IE: when we switch to the top of the list... then everybody is asking which car is #1, and more time has to be spent checking cars more.
I thought about making alternate lists too... but again, the potential for confusion gets burdensome.
EDIT:
Note, I think this is something that needs to be up to the host, because of the
responsibility to keep on the time schedule, etc.
For example, someone hosting that's younger & more spritely than myself
might be able to handle hosting a car-list-shift like that with more people. So like if someone else hosts an event/series, they can make that call, depending on how they're running for time. 👍
EDIT 2:
The reason many of you might not know we've already been doing this is because you were probably not in attendance the times there were so few drivers... for reasons which should be self-evident.
