`bottom(1, scores)`

For best N scores, there are really two ways to do it. Assuming, for example, you are taking the top 15 out of 16, `top(15, scores)` works just fine. It means you're dropping the lowest score. And that's another way to look at. In this case you know there will be 16 tournaments. If in one season you had 20, you'd have to change the formula to `sum(top(19, scores))`. You're still dropping the lowest 1 score. You *could* change it to `sum(top(n - 1, scores))`. `n` is the number of tournaments, so this would always drop the lowest score no matter how many tournaments you have. You wouldn't have to change it for a season in which you had a different number of tournaments. *However*, it always drops a score, no matter how many tournaments you play or how far along the series (or season) you currently are, whereas `sum(top(15, scores))` doesn't drop any scores until you've played at least 16 tournaments.
