Yes. I did!
âIn the betting game: it's my only chance to stop Silver running away into the distance with all his winnings!
Do aliens get turned on by volleyball? it's like they beam him down to commentate on stuff that nobody else wants to do.
He's my driver in the sweepstakes… …
You are quite right that drivers will use the tyres differently; and your comparison guess is indeed part of the problem a race-engineer and his driver face. Driving style and car set-up will also influence the decision (e.g. Alonso wears his fronts more, compared to Hamilton who is heavy on the rear) and the compounds supplied may benefit one style over the other, even requiring a driver to alter style a little in order to exploit the 'best' option (no pun intended).
The calculation compares two or more 'models', and estimates the optimum accumulated time over the total race distance with 'ideal' use of tyres (normally just one stint on the Prime), without taking account of potential difficulties with traffic – which may require some revision of the plan as the action unfolds; offset by the total time lost through pit-stops including car stationary for about 3.4 secondseach. I believe the Option tyre for Hungaroring this year is estimated to be 0.64 seconds quicker per lap on average (at expected temperatures), but of course it degrades sooner and less progressively. All these factors must take account of improving 'idealised' conditions due to fuel losses as well as increased grip as the circuit becomes more rubbered-in towards the end of the race. This is a bigger factor at Hungary than most circuits, due to the fact that it sees very little use throughout the year. It also means that tyre degradation is higher for this circuit than most others, due to the track's dusty, (slippery) nature because it increases 'slip-angle', which tends to scrub and overheat the tyres*.
Once these parameters are understood, computer models can make light of the calculation – and apparently Anderson's an expert with his input!
I'm expecting most teams to do three stints with two on the Options; although this may be compromised by how a driver has used his tyres thus far, and may also require a rethink on-the-fly, if traffic or other circumstances come into play. And whilst I'm on the subject, this is where I feel McLaren have tended to be ponderous with their thinking.

*'Slip-angle' is the difference between the route a tyre takes over the track surface, and the angle it is actually pointing in. As most will know, slip-angle at the front is known as understeer and at the rear is oversteer. Slip-angle generates heat and tends to scrub the tyre, and the two available compounds can be quite different, making these calculations more complicated. Indeed, as has been discussed at length, this has been one of the biggest headaches in trying to get to grips with Pirelli's tyres for this season!
Cheers cosi. Do you think Anderson has calculated his strategies himself assuming a gap between the two compounds and the rate they degrade or do you think he's just got the information from one of the teams?
It's been raining in Hungary, the track will be dry if there's no rain though. Just watched the GP3 race, brilliant wet/dry race, da Costa was excellent, started 8th having won the first race, was up to fourth then pitted for slicks and fought from 9th to 1st. Him and Pal Kiss were over 40 seconds off the lead with 6 laps to go.

Looking back at qualifying does anybody feel angry at Jenson? I mean the guy was 6 tenths off Lewis yesterday and you had people like Seb being kicked out of Q2 in the past when just being 2 tenths off Webber for example.
I don't hate Button but the guy had a **** qualifying attempt and he still makes it into the top 4! Surely I'm not the only one that thinks that's bullshit?
Any other car and he would of been where Webber was I believe.

It's like going back a few years when there were substantial gaps between teams and drivers. This year has been ridiculously close sometimes, as you say 2 tenths being the difference being fastest in Q2 and not mkaing it through at all! Such small margins.
So whats this about then?

Could this be related to claims last year that they had an ajustable rideheight during the race? Could it be done by a small tweek in the pit lane?

Horner claims that they've never once adjusted the car in park ferme. Based on their qualifying pace vs race pace last year I'd say that's worth investigating. Also a case of exact words, as he didn't say anything about during the race...
Basically they had a device which allowed them to do by hand what other teams do using a screwdriver, so naturally everyone assumes they're cheating. If you look through the McLaren thread you'll find a discussion about McLaren being able to change theirs during a pitstop (which is legal), with pitstops being sub 3 seconds now the teams are obviously going to look for ways to reduce the time it takes to adjust the ride height. Like Horner says, it's a non-issue, it's just being made into one for another smear against Red Bull.
Edit: I can't find the discussion in the McLaren thread (I was getting mixed up with the brake cooling adjustments during pitstops), it might be in the Spare Parts thread, I found this from Scarbs though:

Yes.
Anderson understands the factors of the calculation just as well as the teams, except for one relatively minor factor: he doesn't have the precise data which a team will need to make use of. Therefore his predictions are educated guesses based on rough estimates of what he expects this data to be. However, any differences are usually minor when measured against the simple objective of discovering whether 1, 2, 3 (or even 4) stops will give the theoretical quickest solution.
For a moment, remove Hamilton from your assessment. This would show the gaps to be far smaller. When one bears in mind how closely competitive the top teams are this season, what Hamilton did was quite exceptional; effectively distorting the picture. That said, I agree that Button is unlikely to be comfortable with his weekend's performance so far, since it is natural to ask oneself why there is such a difference to one's team mate.
Exactly.
Rain might not be such a good thing for the spectacle, baldy Benson says that the teams are expecting 'downpour style' rain so we could have quite a few safety cars/red flags.
On the plus side it will stay hot so when the rain stops the track will dry out pretty quickly unlike what we had in Silverstone

Holes in the wheels are considered 'moveable aero devices'? seriously the FIA should have a word with themselves if they consider Mercedes front wing staller legal, talk about playing favourites.
The lewis and Fernando love in continues, looks like JB won't be happy!
