Almost always, the proper tap point is found
experimentally as you were doing.  The outputs of
programs like JavaTC are generally used as starting
points.  Have you tried JavaTC? 
(http://www.classictesla.com/java/javatc.html)  The
program is pretty forgiving of partial input; you
don't need to fill in every single one of the zillion
or so boxes to get an idea of where things are going. 
Plug in your primary, secondary, topload, and main
capacitor info, check the "Auto tune" box and click
the "Run JavaTC" button.
