hey Emmett....

yes ... the WinTesla can be confusing in that area..   when you run the 
transformer section it will give you a cap rating for resonate value ( best 
value for the transformer at full power   usually higher than what the coil 
needs as far as cap size)

when you run the secondary coil funtion it will give you a cap rating for 
secondary coil size.

when you run the primary it will give you a cap size for the number of 
turns you put into the primary...   dont forget you need to adust primary 
size for tapping  ( this changes cap value)

best bet is to set up the transformer values , next  set up the secondary 
parameters, next set up the toriod size, and the size of the cap you are or 
planning to use ( these are fixed sizes )   finally set up the primary size 
( shape wire dia. etc.) and now for the magic part to find all the 
numbers...   change the primary # of turns untill the cap size matches the 
actuall size of the cap you are using....   this will give you the tap 
point on the primary you need to use ( +/-) 1/2 a turn
