4 KPH to Verstappen. About the same difference in the low speed corners, where we are consistently faster. That cornering 4kph is a bigger gain to lap time than the 4kph with DRS open. Significantly bigger. But a lot of folk will look at that DRS number and think there is an issue.
Worth stating, that as usual, along the straights we are as fast as RB and Merc until the last fifth of the straight when the drag starts to impact acceleration. Which is, again, why that number is meaningless. It'd be better to post charts with average minimum speeds through the different corner types and the average speed of the whole of the straight.
This would be a much better reflection of how the balance affects speed and lap time.
