From Chapter 7: "All race classes shall be gridded based on season points standing unless otherwise noted. All races are 10 laps unless otherwise noted." I would propose that in the first round of the season, we grid based on last year's standings, with new riders at the back of the grid in a random order.
Well, as it turns out, it's actually covered in Chapter 15. Perhaps this rule could be put into a different spot to make it more obvious? "15. 3 Pre-registration is mandatory; grid positions for the first race of any season shall be based upon previous years finishing order, with late registrations and newcomers gridded behind the returning competitors. Grid positions in subsequent heat races will be based on current point standings of the pre registered riders only, late registrations will be gridded at the back of the field. The decision of the Race Officials shall be final"
