I really think that the engine mapping matter has affected RB, but I don’t know how much, yes, they are faster that these laptimes but I am very doubtful about seeing them in the lap in Australia.

Bear in mind though that the best fuel-corrected laptime might not stem from the outright fastest lap of each team. It's a problem that we all have to contend with and remember. Even if from the same run, the fastest lap in a run might not be the fastest fuel-adjusted laptime. For example a 1:21.000 with 20 laps following it is far more impressive than a 1:20.999 with 2 laps following it, - but the timing system would only register 1:20.999 as the quickest time.

With all this talk of sandbagging, it would be interesting to see if anyone could correlate the fuel-corrected best times for each team, and compare it with the quickest lap they did for the Spanish Grand Prix weekend, for 2011 and 2012, and pick out any trends. Not that I expect anyone to do so, understandably - that would take a mammoth amount of free time.

Prediction to the .001 second? :wtf: :lol: Sorry but thats ridiculous, even if its Gary Anderson...
He's not actually predicting the times in Melbourne, but rather, what he attempted was to make a list of the testing result in Barcelona, that gives the pecking-order down to the 0.001. In other words, he's predicting the Melbourne Qualifying grid as by the performances of the drivers in Barcelona.

From what I can gather, he worked out the numbers by normalizing tyres, fuel load and how the track evolved over the days.

I guess it really is just pure speculation, playing with numbers and coming to some conclusion that can in no way be accurate, but fun all the same. I don't see them all that different than the more transparent "normalizing" of testing-laptimes others have done in this thread or on other sites, without drawing parallels or far fetched conclusions to the Australian qualifying in less than 2 weeks.


What I am actually a bit surprised by is that Rosberg is in front of Hamilton accoarding to his calculations. Even though Rosberg has the quickest lap time of the Barcelona test, I was of the impression that Hamiltons time on soft (1.20.5xx) or the time on medium (1.20.8xx) was very close, going by that Hamilton did more laps after setting that time. If you factor in that the track was likely better as well on the final day when Rosberg drove, would put those times even closer. Not that it really matters, it's all just about understanding the numbers and what influences them that makes this fun. Wouldn't the teams actually be doing the same, just doing that with more data, sound analysis, trying to get an impression on where they and the others are?
Not for nothing, Rosberg's Championship is the only thing that lends credibility to Hamilton's recent success. Otherwise, he'd just be the guy who's had the best car. — bhall II

I stopped reading all these predictions, assumptions, etc. a couple of weeks ago. They're overdoing it at BBC/SKY tbh. They spend tons and tons of time analysing and predicting the times/order, while they have absolutely no idea what the teams REALLY do. I used to like the winter testing to see the technical evolution in F1, but this year it's been absolutely hilarious.

Would love to see a Merc on pole, but we have to be realistic. By the way, I don't take GA serious. He made an u-turn again (Mercedes) just like last year with the MP4-27.

Had anybody stated numbers down to thousandths? This is ridiculous to any person with half decent scientific/engineering background. It's like if you read in a cookbook "get a piece of beef, splash a bit of oil, add a pinch of salt, roast and you would get a 258 gram steak".

Well, if somebody else calculated a lap-times down to thousandths, it would be equally laughable. IIRC most of the "times" I've seen are down to tenths. Which is also not too honest but not quite as much.
Wouldn't the teams actually be doing the same, just doing that with more data, sound analysis, trying to get an impression on where they and the others are?
They would. But I doubt their estimates are down to the third digit.

Do you think if you give a driver a go in a same car/tyres/fuel load... heck, give him a simulator and he'd come down to +/-0.001?

I don't always trust his technical analysis, he seems way off at times, but I do trust his track side impressions. I do believe him that the car initially looked like it understeered and then snap oversteered out of corners. I also believe him when he said the car looks really good now, which drivers and other track side observers have noted. I expect the Mercedes to be in the top 5 spots on the grid when qualifying. I wouldn't be surprised to see one on the front row.

Has anyone considered that Merc may have looked good in testing because they are working the tires harder, getting them up to temp and therefore avoiding the graining that has plagued almost everyone?

And after that doing a good looking long run? Impossible. As Dren said, it isn't one guy who thinks Merc made progress. All the observers made the same comments about Merc.

I'm not discounting your point, or discounting the consensus, its just a question i have been asking myself. I'm not going to pretend i know what i'm talking about regarding tires..but is it not possible to get better wear rates when the tire is up to temperature and developing grip rather than being under temp and the surface is graining, as from what i understand graining is literally the tearing of the surface of the tire (tearing / balling up of rubber)

Like i said, just musing over things..i hope their pace is genuine

For all we know the Merc can be blistering in cold conditions and when it rains.
But hot conditions absolutely terrible.

but from what we have seen, cold, not so cold, rain, it all seems to handle it very well.

Not that I am aware of... then again, if it's that big of a bother, just ignore the last digit(s). It's not as if these values or predictions (whatever you want to call them) are ment to be exactly scientific. I can imagine he probably took the lap times, normalized them using a metric he thought to be quite accurate (softer tyre -0.5s / track evolution perhaps a factor of -0.x a day) and ended up with the figures he did and instead of rounding them up - or perhaps putting down a +/- 0.2s as he should have done, he just left them as is, down to the 0.001s. Not exactly the way I would do things on my blog or when writing an article.

I'm sure the lap times that were normalized here were rounded at some point too to the n'th digit (probably after the normalization for as little error as possible). This one wasn't, obviously, but I don't think it's worth getting to worked up about it.

BTW: I'm not defending the validy of the numbers in any way. Just my two cents on how he derived them, that's all.
