Craig,

  I see no need to count. For all long lead components,
I soldered lots of them in before trimming the leads.
When I started to trim them, I checked if I had soldered
before snipping - caught a few that way.
   ICs - I soldered the corners first so that it's easy
to see one not filled in and make sure no end ones are
 left out.
