At least we are learning more about some of the top speed issue. I'd rather it be because of DF rather than aero inefficiency or deployment.
It may not be optimal in Q but it will become more beneficial in the race, it certainly feels like they had one eye on the race with this set up. Especially if there is any kind of rain.
Of course it will not only improve race pace but also tyre life and strategic options.
For several of those first laps we should be able to run behind cars for a tow and then DRS negating further that drag penalty.
And the opening laps with warmer tyres will be yet more effective with the added DF, so look for some action here too.
Edit: I'm sure we can be more efficient, of course, it's just I'm not sure it's a big issue on this car with DRS closed.
