Balance of the car looks really good. Norris seems to be preserving the tyres well also. But the car is too slow to overtake. Even when Hulk lost DRS, Norris even with DRS could not catch up. Maybe better to pit for a new set and try to undercut. But with potential SC very tricky also..
Edit: forgot Ocon and Hulk still need to pit. So not that bad of a position. Just have to wait a while longer.
