Per-race scoring options

How much a particular race counts, as a NoR or SI may specify it: a race marked "must count" is never discarded, a race marked "discard first" is taken before any other when discards are selected, and a weighting makes a race count for more or less than one (×2 for a trophy race, ×0.5 for a lesser one). Weighting a race up does not protect it from discard — an SI that wants both says both — and the weighted score is the one discard selection and the RRS A8.1 tie-break compare.

Examples

#	Scenario
1	Per-race options — a race marked 'must count' is never discarded, even when it is a boat's worst
2	Per-race options — a race marked 'discard first' is dropped before any other, whatever the points
3	Per-race options — 'discard first' and 'must count' races in the same series, with two discards
4	Per-race options — 'must count' and a DNE are different protections, and both apply at once
5	Per-race options — a race weighted ×2 is not protected by the weighting, and discards on its weighted score
6	Per-race options — a race weighted ×0.5 counts half, changing which race each boat discards
7	Per-race options — a ×1.5 weighting on a shared place, rounded to a tenth
8	Per-race options — weighted scores are what the A8.1 tie-break compares
