Clutch

Only clutch when there's nothing to land on within this many blocks below you. A catch may drop you this far (never far enough to hurt) to use fewer blocks.

Fastest the aim turns, in degrees a tick (random in this range, picked again every tick). It speeds up to this and slows down onto the spot.

Milliseconds after you go over the edge before it starts turning (random in this range).

Most blocks it places for one fall.

Which blocks it places. Solid blocks skip anything that falls, explodes or opens; pick exceptions in the library.

Swing your hand when it places (off: the swing still goes to the server).

Go back to the slot you had afterwards.
