Default Hot Whirlpool

I've seen several recipies that call for an extended 'Hot Whirlpool'. My question is, how hot is hot? I normally whirlpool for 10 mins or so before kicking on the chiller, but for an extended whirlpool, how high to I need to keep the temp? I'm guessing above 160 or so?

There's an article floating around here somewhere that talks about hop utilization and temperature. I believe that alpha isomerization drops by 50% for every 10ºC. When the big boys whirlpool, they're doing it right below boiling. If the recipe doesn't specify otherwise, that's what I'd do.
