Thats just silly.

Yes I agree that Ferrari are ahead, but not necessarily in their own class.
If MS was driving, then maybe. I think Mclaren will see more that an
opportunistic win. But I'm not sure about BMW. I think that if they continue
to develop they might get more. Perhaps a win in their own right.

Hmm, not sure I agree. I think the gap between Mclaren and Ferrari is bigger
than the Mclaren BMW gap. But, like you say, different circuits will suit
different teams better. Whatever the case, the season will tell. Obviously I
hope Im wrong......

I do see your point about the engine freeze helping bunch up the field. I'd
forgotten all about that!!!

I've just run another little exercise to verify my estimate of 0.09 seconds
per lap's worth of fuel. I've taken the best time for each driver in Q1 or
Q2, deducted that from the Q3 time and divided by the number of laps fuel
they each had in the car during Q3. I've also adjusted that number of laps
for the safety car period of 3 laps in which I estimate they'd have only
used 1 lap's worth of fuel so without the SC period they'd have all had to
pit 2 laps earlier than they actually did.

Calculating that out for all 9 drivers and averaging it came to just under
0.08s per lap not 0.09. However not every driver, especially the fastest
ones, would have needed to have gone as fast in Q1 or Q2 to make the top ten
as they possibly could have so this would lead to a slightly low estimate
for the time per lap of fuel. Kimi for example only gained 0.062s per lap
and Lewis 0.067 whereas Trulli at the bottom of the order gained the full
0.090s. On that basis 0.09s wasn't far out but using 0.08 didn't change the
true pace order I came up with first time. My final best estimate is that
0.085s per lap is about the right figure. That would also equate very
closely with Brundle's estimate of 3 tenths per 10kg of fuel.

I think the biggest thing that strikes me about this is that the fragile
Alonso ego we saw last year at McLaren must be still very much in evidence
if he was prepared to sacrifice so much race potential just to qualify
higher than the car merited at his home GP. I'm also very surprised that the
team was prepared to go along with this.

Finally, after adjusting for the safety car period and excluding Fred, the
average intended first pitstop for the other eight drivers was lap 19, or 3
laps earlier than the theoretical ideal of 1/3 of the way through the race.
I'll see how this compares in future races.

My data if anyone wants to try their own analysis came from this handy site.

And yet it was _such_ a good idea for Lewis to run 4 laps less fuel than
Alonso at Silverstone last season, huh? Was Lewis ego fragile then?

And how'd that work out for him relative to his competition in that race?

To discuss Alonso further - it succeeded in getting him ahead of his real
competition (everyone behind the top 6 cars) and maybe even Heidfeld.

Semi 'official' figures for Catalunya, maybe from 2006, were fuel burned per
lap 2.22 kg, lap time reduction for 10 kg of fuel = 0.42s per lap. Those
do equate to 0.09s.

These were the 10 quickest times over the whole weekend:

Hamilton Q2 1'20.285
Massa Q2 1'20.584
Kubica Q2 1'20.597
Räikkönen P1 1'20.649
Alonso Q2 1'20.804
Heidfeld Q2 1'20.815
Kovalainen Q2 1'20.817
Piquet Q2 1'20.894
Trulli Q2 1'20.907
Webber Q2 1'20.984

They might be assumed to be the absolute quickest laps possible with 'zero'
fuel.

Dave, we all know you detest Alonso - you go to great lengths to find
sticks to beat him with, but now you're just being a blinkered plonker.
There's more to Renault's choices than mere statistics. Note the
emphasis here on the word "Renault". Not Alonso.

Pat Symonds repeatedly went on record this weekend saying how pleased he
was with himself and the team, in that Renault were regaining their
reputation for creative strategic thinking. Once again : Renault. There
was no "the team going along with Fred's ego". It was the *team's* idea,
and they knew that Fred was a good enough driver to be able to make it
work.

Here's a clue for you, copypasted from another post of mine :

On French TV, the commentators were saying that Carlos Ghosn recently
warned Renault F1 in no uncertain terms that Renault must be "part of
the show" i.e. not trundling around unseen in the midfield. Or else.

For me, the strategy employed by the team this weekend was a win-win. As
far as I can see there were no real disadvantages. It boosted team
morale, it put the wind up the opposition to some extent, it boosted
Alonso in Spain, and it got plenty of "Renault are back!" press and TV.
On top of that, he was headed for a very respectable result on the track
till the engine blew.

What's not to like?

While I do find your OP of interest in as much as I find normalised Q3
figures of interest (please do continue to produce them) it is a shame
you undermine them with rather poor and clearly prejudice opinion of
Alonso.

I am not convinced that Alonso strategy was a poor one and Renault
obviously did a damn good job of making the wekend more interesting
whatever the driving motivation.

It is one thing to take the piss out of the Brendas for their devoted
prejudice, another to join them.

Looks like Heikki would have gone a few laps longer than LH:

* en.f1-live . com /f1/en/headlines/news/detail/080428144308.shtml

"He had still to pit for fuel at the time of the accident and wasn't

the fuel load he was carrying during qualifying, when he did an
absolutely fantastic lap."

Has LH been lighter in every qual session so far than HK?

He might have, but you can't conclude that from what was said.

It looks like a question not a conclusion.

The answer is probably yes.

Massa did his best time on his first run, so he carried something like
three laps more fuel on that lap. If you take that away his time would have
been around 21.970, which seems more in line.

The Renault flatteration factor depends on how you are comparing Alonso
time. But yeah, BMW and McLaren are the most obvious ones and .450 is still
quite a lot. Might be realisticly even more, since that last lap by Alonso
seemed to be rather good, he was half a tenth slower than Hamilton on the
first runs.

So you actually had already taken that into account and had that final run
there. Good job ;)
