Still, I would like to see some real data and not just conjecture. If the delta isn’t great, if fresh air can get between the heat exchangers because of a high pressure area around a low pressure area, if the frontal area of the cooler isn’t significant enough in size to cause a change in IATs, if the circumstances that warrant concern are only in the most extreme applications, etc, then there may be no reason to justify divorcing all the exchangers.

I pretty much agree. I'd just have no way to corollate any data that I could gather to IAT's.
