Thanks. Like you, I wasn't interested in processing at cooler temperatures. My radius/target is still 100F.

It was this post by PE that got me to consider the idea seriously:

Or. to quote:
I set the temp to about 102 and let it drop to about 98 over the 3'15" development time. It works just fine. Temperature averaging, as it is called, is mentioned on the EK web site.
