The rail room
Tempo is the shift. Height is the follow.
We time the arc a player actually writes. Then we match CG height so Kern heat cannot turn a slow swing into a balloon or a fast swing into a worm.
A catalog sticker is a social object. Valley heat is a foreman. If the height does not follow the arc, we will not stamp the sticker.
Ozzie will stop a session that wants a brand before the metronome has a number. That is the rail personality.
