The nice value is an integer from -20 to 20. -20 is the highest priority
and 20 is the lowest.

man nice will tell you a little bit, although I assume you've already read
that.

There's a pretty good coverage of the BSD scheduler in "The Design and
Implementation of the 4.4BSD Operating System" by McKusick et al and while
NetBSD might be a little different nowadays [I'm not sure how much the
scheduler has changed - anyone?], the principles are unlikely to have
changed too much.
