Consider wiring a voltmeter in semi-permanent connected to the tag that 
operates the
solenoid and the body of the starter.  That should tell you if the problem is 
internal to the starter/solenoid or external.  

In my youth I had a Mini van that started doing your 0.5, and wisdom among my 
was 'dirty pinion, wash it in petrol'.  It worked for a week.  After several 
I got fed up and consulted a member of the Badger Club (someone with grey 
'Put a little light oil on it and wipe off any excess'.  Never had any more 
with it.  Your new starter may be too dry.
