[f1tv2020testa]Norris said he could feel improvements in his driving after his first full day in the McLaren:

A tough day, especially for the neck, but it was productive. I think a lot of things learned for the team, a lot of things than for me and already I feel like I’ve improved on a couple of things which I wanted to improve on such as the long-run pace and management of tyres and so on.

We did a variation of a lot of things, the aerodynamic runs with the rakes on. No low-fuel stuff because no one ever does them. A lot of high fuel, a lot of set-up changes, trying to get an understanding of what this car does and how set-up changes affect this car course because even though you do ride height or front wing or rear wing or something it can still affect the car in different ways to last year.

So just trying to get a bit of a reading for how this car changes and drives compared to last year. But apart from that, pretty straightforward.
