Downbearing - Setting with a loose board

I'll venture to ask these questions, even if the answers are obvious to 
those more experienced.

Do you think that the results obtained using the pre-load method are (or 
can be)  equivalent to the method you describe? Is there a significant 
advantage to your method?   Is there a way you factor in differences in 
panel flexibility?  What are stringing pillows?

RonN - I know you said you "have" employed this method, which I interpret 
to mean you may use others as well.  Is this accurate?
