Telemetry chart - McLaren Spa 2012

[Shrieker]

I don't know (can't tell) which corners he is earlier on the the throttle, but apart from the slow ones it makes sense since Lewis was running much more df at the rear, typically this will cause the car to be a little bit more understeery in the exits of fast and medium speed corners.

Bigger picture:
This is a telemetry comparison between Lewis Hamilton and Jenson Button's qualifying laps at Spa. Lewis is the brown trace, Jenson the blue.

The top line (slightly cut off) could be kers, DRS, or something like that. I don't know.
The next line is a speed comparison. You can see that Lewis is slower at the top end along the Kemmel straight and into the Bus Stop, but faster through most of sector 2. This is due to his high downforce rear wing. It is interesting that the line is never flat, so the car never reaches top speed.
The second line which is rougher and more up and down is the steering angle. <Edit> Right is up. (Thanks for pointing that out gato azul)
The dotted, annotated line is the time delta, which is of course related to the speed traces. Lewis is clearly not happy with his lack of top speed.
Below that, the stepped line is the gear selection. The seventh gear selection point is slightly different between the drivers - either the gear ratios were different or the wing made that difference.
The very bottom lines are throttle and brakes.

As for the things on the top left, we know that the length in mm is ride height (Lewis is 0.1mm lower than Jenson). The rest I don't know. It would be fun to speculate though.

If you want to know more about telemetry reading there are some good examples (ironically published by Mclaren, two days before Lewis's tweet.):

I think it´s just making him a human being jt.and as you already stated ..it does not give away much really :there is more than one way to get a laptime...same car different setup still the cars potential is basically the same.And it tells a story about the potential of aero development ...adding DF .
More is not always better...

The second line which is rougher and more up and down is the steering angle. Left is up.

are you sure about this
I always thought "La Source" is a right hand corner.

This one is certain. It agrees with relative change of direction from corner to corner.

Actually, Button trace looks very good in the second sector too. He looses something on braking and earlier acceleration but his apex speed thru many corners is as good as Lewis'

This is due to his high downforce rear wing. It is interesting that the line is never flat, so the car never reaches top speed.

Don't forget that the gearing was chosen before Lewis decided to switch to the old rear wing, so he had the wrong gearing for the level of downforce he was running. This really would have hurt him.

Why did Hamilton share this with us?

Why did Hamilton share this with us?

I get he felt he needs to show why he suddenly was of no competition to Button. Those guys are tough headed and Hamilton is certainly not used to be that far from a team-mate in a normal conditions.

And that's fair enough. But, wasn't he intimately involved with the decision to go with the terrible setup that produced the discrepancy he illustrated for the world to see?

To me, this just seems like a really short-sighted move on his part, which is probably why the image was quickly removed. All he's done here is show us that either he wasn't able to discern the right choice from the wrong choice or he wasn't able to convince his team that he could discern the right choice from the wrong choice.

I think he was trying to rub the team's nose in his poor setup, but no one has more power over a car's setup than its driver.

It's just puzzling.

I don't think he was blaming the team in terms of being "given" a bad setup. I think he wanted to justify to the world the situation of himself being 8 tenths off Jenson's pace.

Wasn't his very obvious different setup and the many, many, many explanations of said setup enough? I'm really not trying to be difficult here. I'm just genuinely struggling to understand the logic behind posting that telemetry.

Some things have absolutely no logic and as seeing that this is from Hamilton, I'm sure this is one of those occasions.

Well, I feel it is short sighted too, but out of top-teams I guess he is the most prone to such moves.
Still, I totally understand how they might came to wrong setup given that they had only Saturday's practice for dry running and it axtually wasn't perfectly dry.

May I add the fact that he had 2 consecutive tweets cancelled by team request? This was the second one, the first was something like "team gave me a wing I didn't like at all" or something similar.
It's perplexing, given the fact he hasn't renewed his contract.
