He apparently does not need to spend time building up as a driver, and can immediately give the team top-level feedback about the car behavior at its limit.
See, see what I mean mep ... assuming Mr Shoe has guessed the same as everyone else here has, or maybe he hasn't, does the evidence of a single plot make his emphatic sounding assertion valid? Does he convince you? Does the plot alone convince you?

It does not include many basic and obvious things you would want to see if you were analyzing the differences in vehicle dynamics. This suggests the team also sees the difference as driving rather than setup.
Of course, that is because it is the driver printout ... the team deliberately choose only to present to a driver the thinnest subset of data that is related directly to the things he is touching; the pedals he pressed, the gear he selected, the steering he turned, the wing and battery buttons he pushed ... and then overlaid the resultant time delta.
That sheet is not for the team, it for the driver to have a glance at.
(How genuinely real-world helpful it is, diving into a braking zone, is another question. I'd be curious to know how much of Hamilton's four-tenths in Nurburgring Q3 was based on a two-color inkjet versus what he feels the car to be doing right there, right now. I'm skeptical).
Race engineering, the team, doesn't much use that printout, they are using their own slices through the telemetry datasets, their own setup sheets, their own analysis of vehicle dynamics, cross referenced to pre-rolled computer simulation, factory evaluations and historical data from other sessions, atmospherics, tyre data, engine data, strain gauges and load cells, in other words the reams of paperwork and racks of fileservers, laptops and datalinks that is required by motorhomes full of experienced, professional engineers to begin to even contemplate making a meaningful statement on any given laptime, and still sometimes get it wrong ... if you were in the mood to be less verbose, that laundry list of vital information is more usually described "the stuff you don't have".
Notice, we are now three pages into this, and nothing definitive has been able to be stated about anything whatsoever, every conclusion is always a question.
Pretty picture. Pretty colors.
