And don't you want warmer oil when you're in efficient mode so that you can burn off the water in the oil and keep the engine as efficient as possible for daily driving? Once the thermostat is open (or you've put it in Sport + mode) the oil is now flowing to the oil cooler and will cool the oil until it reaches the temperature the ECU has deemed to be cool enough and then it closes. Does the flow increase measurably in that situation too?

These points are why I can't see myself bothering with this. On the street it's arguably not as good for the engine as running hotter, especially since the S55 doesn't run too hot anyway. If you're tracking, you've either got enough cooling capacity or you don't and a thermostat that opens a little earlier doesn't matter. Maybe if you've got huge power and only do drag racing.
