What is the right Dwell?

["Anthony Rhodes" <spamiam@comcast.net>]

Can anybody confirm the dwell reading for a TR4a (or Tr4, and probably TR3
too!) when the points are set properly?

I think I have the points set right.  I always find it hard to judge the
last thou or two on spring-loaded parts.

I get just about exactly 60 degrees dwell. Is this what I should be seeing?
