Discussions on how hard to run your setup.

[BamaBill]

Guys, I run two pot and thumper setups. My original 7gal stove top and a 15gal keg and thumper. From day one, I have run them more or less low and slow. Sometimes I have ran it a little harder if pressed for time with no loss in product.
So, recently a buddy and me were discussing how hard we run vs how hard we could possibly run our setup's. Typically in a 15 gal mash, I'm keeping 2 gallons of 110proof.
So, my thoughts are, if I ran it harder and faster... As long as I don't push more vapor than the condenser can handle... The alcohol has to be in the pot, in the thumper or it condenses into my jar. And therfore, no loss in capacity.
Thoughts?
