I haven't read every post in total detail but from the few I've read, stirring a pot with a paddle for two minutes isn't going to give you remotely what you're looking for.
I have a couple of different circuits that connect to my BK. One is from the BK, to a pump, through a plate chiller and back into the BK for chilling. Another is simply the BK, through the pump, and back to the BK with a curved "outlet" in the BK that I use for whirlpooling.
AFter chilling, I let the whirlpool go a solid half an hour with the March 809 and valves opened completely and every time I end up with a tight little pile of trub at the end. I can then drain off my BK into the fermenter and leave that pile of trub behind.
Like I was saying, stirring it with a paddle isn't going to get you there.
Is it a big deal to get all of that trub out? Not really. When I was building my rig, I planned for the whirlpool capability and its a "nice to have" but I wouldn't sit there for 30 minutes stirring with a paddle to get it.
