So in reading this correctly, seems the flavor and possibly to a lesser extent, aroma hop additions should be augmented by adding the hops in a whirlpool of 170*? I am envisioning being at flameout, crank up the pump, get the whirlpool rolling, then route the wort through the therminator (without running the cooling water). Once the temp reads 180* shut down the pump and add the hops. Sit for 20 mins then cool the wort to pitching temp and go to fermentor.
What I do is at flameout recirculate through my plate chiller until I hit 170F, then just turn off the water running through the chiller and keep recirculating. I usually recirculate for 20 -30 min, the temp will drift from 170F down to 160F.

Cheers.

What I have found to yield the best flavor and aroma is to crash as quickly as possible at the end of the boil after adding the last addition.

As for how steeping time effects flavor and aroma I have a recent example of that. A few months ago I made another batch of Boston Lager clone. This is one of my favorite beers and I like to have it on tap at all times. The brew day went great, but when I went to chill via whirlpool IC I got nothing when I turned on the faucet. The hose had frozen solid. 15 minutes of messing with the hose and 15 minutes of rigging up another cooling solution later I got the beer chilling. Where it normally takes me <5 minutes to get below 120 it had taken me ~30. There is very little hop flavor or aroma in that batch as a result. If I didn't know better I would say it wasn't the BL clone recipe at all, it tastes that different.

A point to remember is that if you are trying to clone a commercial brew then a whirlpool/hopstand step is going to be critical to get the same character in your finished beer. You need to get your process as close to theirs as possible to have success, and a commercial brewery just can't chill their batch as fast as we homebrewers can. They may have a 30 minute whirlpool that reduces hop flavor/aroma and adds bitterness. Large doses of dry hops are often used to offset this loss of volatile hop compounds.

I pulled the recipe from the BeerSmith database. This is very close to the real thing:

http://beersmithrecipes.com/viewreci...on-lager-clone

Last time I brewed it I added .75 oz hallertauer for the 5 minute addition and threw in 1 ounce at flameout. This gave me more flavor and aroma without having to dry hop, which I am (sadly) too lazy to do most of the time It had a bit more hop flavor than the real deal but I really like it.

if you read the article linked above, you can see that Brad Smith recommends an estimate of about 10% ibu utilization from your hopstand addition.
BUT if you head on over to beersmith 2, click on preferences, then bitterness, you'll see the settings are actually set to 50% for hopstand/whirlpool. under the description for that it says
"steep/whirlpool factor is a percent of equivalent boiled hops. Should be set to 50% for a steep temperature of 90C/194F."
Seems to me by that description that it is accounting for extra isomerization by all hops added during the boil. hence why the IBUs stated for your whirlpool additions will be higher than your late boil additions. it is simply putting the extra IBUs in that line, maybe it made the programming easier.
i will say, if you ever have any questions about beersmith, one of the best ways to get an answer is simply to email Brad Smith. I did once and got a quicker than expected answer.
