Although not precisely an answer to pjcampbell...I wanted to share an experience that I hope will be of interest...
I had made an 11 gallon batch of IPA...adjusted hop additions according to the table in this thread and just prior to draining the boil kettle into 2 7.9 gallon bucket for no-chill, I decided the try something. My brother had happened across a large amount of wild hops that I'd previously used to successfully dry hop a growler of IPA...and he had given me several ounces so, on a whim I threw 2 ounces into one bucket. "racked" the cooled wort off the wild hops 2 days later but did not rack the other bucket. Then pitched both with 1/2 of a huge starter I'd made. Other than that the two buckets were treated 100% the same.
The "hot hopped in no-chill vessel" batch is FAR superior. There is a beautiful mellow and distinct hop flavor to the brew the other lacks. Sadly it's almost gone (I bottle, therefore I horde). I had read about vessel hopping with no-chill but wanted to share this reasonably scientific experiment result.
I have since abandoned no-chill because I felt like it created another "day" of brewing work (not a whole day obviously) with oxygenating, pitching, cleaning up, etc. But I may revisit it if I can't replicate that wonderful mellow hoppy-ness...I am now experimenting with pausing the chill-down at 185* for 10 minutes to hop then restarting the immersion chiller...off topic for this thread...sorry.
