Being in FL, he's going to be near or in that timing reduction threshold a majority of the time because the daily driving will heat up any IC fairly quickly, especially in normal driving. Sure, glory runs on a cold motor and cold IC may show slightly less increase in IAT over the run, but is that really representative of the real world or real track driving?
I think some folks believe that a "good" IC should maintain ambient IATs all the time. Good luck with that.

You’re missing the point. A good IC is all about the reduction of IAT rise in each gear. 10-15F is one gear is not good regardless of ambient temps. Take a look at some of the IC/IAT logs I’ve posted.
Even if timing isn’t being pulled from IATs <110F, the cooler your charge air, the more power you make.
He already knows this and is why he’s switching to a larger IC soon.
