The important point to remember for those components that use static
pressure data is that it be "quiet". No airflow burbles to upset what
should be a solid reference point.

one other comment on the static source: the a/p doesn't care
how accurate the static source is, only that it changes with
altitude. Therefore some people have found that (on spam cans)
putting a dedicated static port in just for the pressure transducer works
well.
...or you can just use the vents to fine tune your altitude....
