gollark: DC is made of numbers, in the purely useless sense.
gollark: Basicallyscore = views + unique views * 6 + clicks * 12if hatchling, optimal score is 13000 at 4d and 5000 at 7d (between the two extremes, it's averaged)if egg, optimal score is 5000 at 4d and 0 at 7d (averaged again)it's safeish if the score is less than 1.5x the optimal score.
gollark: ```javascriptfunction getScore(dragon) { return dragon.views + (dragon.uniqueViews * 6) + (dragon.clicks * 12);}const nextStageAge = 72;const maxTime = 168;function getOptimalScore(dragon) { const time = dragon.hoursRemaining; const age = maxTime - time; if (dragon.type == "hatchling") { return 5000 + (8000 * (age / nextStageAge)); } else { return 5000 * (age / nextStageAge); }}function getScoreRatio(dragon) { return getScore(dragon) / getOptimalScore(dragon);}function isSafe(dragon) { return getScoreRatio(dragon) < 1.5;}```
gollark: I guess that since I'm banned anyway I might as well show my modified EATW formula...
gollark: I mean, it'd be hard to viewbomb something that old.
