I’m curious to know if the median range of deviation for movements fall within more the +6 range. It would appear that most run fast rather than slow. Was it divised for automatic movements or mechanical?

Years ago I took a celestial navaigation course and became intrigued with the history. I guess it’s a nerd subject but I’m interested
