Will John's air conditioner test find at least 50% better temperature delta with two hoses compared to one hose?

Update: took a first pass at this today, experiment ran into some issues (including one issue which was pre-registered as an invalidate-and-retry condition). Details and current planned changes for the next attempt are here: https://www.lesswrong.com/posts/puv8fRDCH9jx5yhbX/johnswentworth-s-shortform?commentId=AeKtgW5JWWaK8qfdJ
I am not an engineer or physicist. I reckon the single host has a compensating advantage. The temp difference between the hot part of the heat exchange and the passing air will be higher for a single hose. Lets say outside temp is 40c, inside is 25c, maybe heat coil is 60c? then there is a 35c difference instead of 20c. So here it will be more effective.
