When assessing compliance, the temperature of the air will be the lap average recorded by an FIA approved and sealed sensor located in an FIA approved location situated in the engine plenum, during every lap of the qualifying practice session and the race. The first lap of the race, laps carried out whilst the safety car is deployed, laps with a time at least 20% greater than the fastest lap of the session, pit in and out laps and any laps that are obvious anomalies (as judged by the technical delegate) will not be used to assess the average temperature. The ambient temperature will be that recorded by the FIA appointed weather service provider. This information will also be displayed on the timing monitors.
Hmmm. Given the intense and pedantic effort spent trying to gain any hidden advantage via clever interpretation of the rules, I wonder how much Merc would invest.
If the plenum does have to do with "supercooling" as the-race indicates, maybe it's only used for the first race lap, in-laps, and out-laps. And perhaps safety car laps where it can be used for efficiency/extra cooling purposes. Those race events (1st lap, in/out) are quite important, perhaps nearly as important as Q3. If they can supercool during those 3-7 laps per race and not fall out of compliance, maybe the advantage is well worth it.
Lots of conjecture here, so this could be way off the mark.
