He was hopping too often, and too far. Fixed.
Update from 1.1 — About Slicky → Install and Restart, or
brew upgrade --cask --greedy slicky. Fresh install:
brew tap ananthasharma/tap
brew trust ananthasharma/tap
brew install --cask slicky
Calmer
Hop distance used to be measured in absolute points, which meant the same
slider position produced wildly different behaviour depending on how big he
was. At his smallest size an 820pt setting is nine of his own body lengths,
every time — frantic rather than playful. Trips now scale with his size, so
a Guppy goes a shorter way than a Whale does.
Distance is also drawn from a weighted roll instead of a flat one, so most moves
are short and the long ones stay rare enough to be worth watching. And about one
wait in four is stretched, so he settles rather than paces — a pet that moves on
a metronome isn't restful to have around.
At one reporter's settings the median hop went from 530pt to 167pt without them
touching a slider.
The default wait is now 75 seconds, up from 25. A minute and a quarter is
noticeable without being an interruption. Existing installs keep whatever you
set; the slider is in Behaviour.
