Ranks and difficulty

Two different questions people ask about Kacky: how far did I get, and how hard is this map? Ranks answer the first. Difficulty answers the second.

Ranks: how much of an event you finished

Kacky ranks you by how many of an event's maps you've finished — not by your times. Clear enough of them and you earn a tier:

Tier	Roughly
Plastic	~10% of the maps
Bronze	~30%
Silver	~50%
Gold	~80%
Kacky	100% — every single map

The exact cutoffs are worked out per event, because events don't all have the same number of maps. The percentages stay about the same; the actual number of maps behind each tier is rounded to something clean for that event. The idea never changes: finish more maps, climb higher.

Getting Kacky — every single map in an event — is the tier people chase hardest. It means you beat the whole thing.

First blood

The first person to finish a brand-new map after an event starts gets first blood on it. It's a small bragging right, and only one player per map can ever have it.

Difficulty: how hard a map is

Every map also carries a difficulty — a rough measure of how tough it is to finish. The harder a map, the fewer people manage to clear it, so a map's difficulty and its finisher count tend to move together: brutal maps have short finisher lists.
