It ain't broke. . . leave it alone. The only real exceptions are for those bikes with the tire warmers and perhaps those bikes that use the roller starter thingies.
First come, first served. You get to run as often as you can - weather and conditions, and number of entrants permitting.
You see someone cutting the line, have a conversation and if that doesn't fix it then refer the matter to one of the volunteers running the starting area. Be happy with whatever the outcome is even if you have a different view.
Otherwise we might end up with one of those rules-deals where you line up A to Z, by age, tallest first, except Sunday on even numbered months for cars with numbers ending in even numbers and bikes with odd numbers, ladies before men.
I can understand why Elmo has the rules for starting position . . . considering their changing surface conditions, points, etc. Maxton really does not have to be concerned with that. The concrete doesn't change as the meet progresses.
