Yes, I would advise never run in Recirculate. The cool exhausted cabin air is of more value to cool the battery than the cost to cool down new air coming into the cabin.
In addition I would advise running the cabin fan with the windows up even when the AC is not needed.
I use Recirculate to block exhaust fumes more than as an energy saver. I still have 12 bars and 89% SOH, and my lease is ending in the next 12 months, so I'll keep up what I'm doing. If this info proves true, it will help those who regularly avoid A/C use to extend range, to reconsider.
