Telemetry and Data of 2011 Monaco GP - Scarb's blog

I take it then; you've worked out who the two are?

I'm pretty sure I know who it is, suffice as to say... You would normally expect the one exerting higher break pressure to out qualify the other, but special circumstances^W^W idiocy occurred in monaco.

At least that's my bet.

[timbo]

Well, if those traces are from FP1 and both are fastest laps for both drivers, than there's only one pair within same distance...

[satlan]

I take it then; you've worked out who the two are?

Yes.

But I don't think knowing who the 2 drivers were was worth that much because both drivers weren't driving at the max, and like someone here said they even had some engine "issues". However I enjoyed scarbs' article and I hope no one will reveal who they were because I do not wanna deprive other people from reading it (because he said he would remove it).

Yep it's pretty easy to find out from which Team/driver this sheet is, if it's true that it is from FP1.

[jamsbong]

I can see how team mates can read each other's telemetry and improve their skills in attacking the corners. I wonder if drivers feel that they are giving away valuable experience by sharing telemetry with team mate.

[raymondu999]

Unless the two are using highly similar setups, it would be slightly moot though; no? For example if someone slides the car a bit like a Hamilton or a Vettel, the way they attack the corners, position the cars, etc would be slightly different to a Button or a Webber who "leans" more on the car's grip, no?

[jamsbong]

Sliding or grippy approach to cornering only applies for slow tight corners. Highspeed tends to be approached in similar fashion by all drivers. I can see this type of corners being helpful by studying faster driver's telemetry. Moreover, blind corners can be learnt more quickly from telemetry.

[raymondu999]

Yes high speed; but I mean, generally, if they have different driving styles/needs, it would be quite different. Fast corners, yes, there's not much to be different on. But when you have, for example, a driver who late-apex'es every corner, and another who uses a "normal," geometric racing line through the corners will not (I suspect) learn much from each other's telemetry methinks.

[jamsbong]

Maybe not from the telemetry alone but with an onboard video, you can definitely learn from another driver. As long as it is worth it i.e. your team mate is faster on that sector, it is definitely worth digging into what makes him faster.
I guess it is not always possible to 'copy' their moves even if you're bombarded with all these data. But if u can, you'll definitely improve quickly.

[raymondu999]

Maybe to learn a track video would be more useful; but IMO to gain that extra few tenths telemetry would work better, no? An overlay would provide a good visual reference as to how much later to be on the brakes/speed to carry through/earlier on the power etc. What can be taken from video would probably be more technique in terms of racing lines and/or certain ways to position a car through a specific corner (e.g. if there actually is a "trick" that isn't very obvious, like maybe staying at the right initially at the exit of the Ascari chicane to miss the bumps)

[jamsbong]

agreed.

All I can say is many many thanks to the people who made it possible that we can see such a printout.
=D>

On the other hand it is just sad to see the reactions on this "technical forum".
Of course you can't really compare the two drivers because the red one obviously was just cruising around but that is not the main point there.
In the past we have seen users here spending lots of time with high end math to get something not even close to this. Now we get everything served on a silver plate and ignorant users complain it is just a nice picture and they can't learn anything from it. Omg it is frustrating to see how the level has dropped here.


Lots of information can be squeezed out of this picture.
When you invest some time into those raw data you can get a good idea of the car and its performance. Things like acceleration/braking/cornering performance comes to my mind. With this you can make rough assumptions about drag, downforce, engine power, gear ratios.
Also it is impressive to see the inputs of the blue driver to the car. How he applied throttle and brake etc etc.

[bill shoe]

Lots of great things to notice.

There are several occasions where blue (faster driver) stays in a higher gear, while red goes for a lower ratio. Red might need a lower gear due to being slower in those sections. However, the extra downshift may be a significant part of what causes red to be slower.

Going into the tunnel, it looks like peak accel isn't achieved until 3rd gear (I believe this is correct but it would be more clear if the x-axis was time). Peak accel in 3rd gear makes sense due to increasing downforce. However, if peak accel occurs in 3rd gear then what is the purpose of 1st and 2nd? The first two ratios may have use from a standing start but why use them once you are moving? Why downshift to 1st in the hairpin if you don't even go to 100% throttle coming out of the hairpin?

[bill shoe]

Another interesting point. Both drivers are shown steering violently to the right at the apex of the (left direction) hairpin. This does not correspond with large throttle input, therefore I assume powersliding is not occuring. I assume the steering rotation sensor maxes out at 180 degrees even though the steering lock can go slightly further, and this briefly reverses the output of the steering sensor.

[bill shoe]

Also it is impressive to see the inputs of the blue driver to the car. How he applied throttle and brake etc etc.

I am also really impressed. Blue is making very firm and decisive inputs. He leaves (apparently) little or no room for error. I would expect this in qualy, but this is very impressive for a practice session.

OK, I'll stop posting for a little while. If you can print out the data on an 11 x 17 (inch) sheet then I highly recommend it.
