I'm one of them too:)

I agree.My mistake was I thought in my previous
post,by Q factor,you meant a classicaly defined
quality factor of a secondary circuit (like in radio
theory) .

On the other hand IMO ,in a real world,considering any
given secondary coil, "Q" in your equation Vs=Q*Vp  
must be conected in a sort of way with overall
efficiency of TC system  as well.
