Spanish Grand Prix 2011, Circuit de Catalunya- Race 5/19

The amount this Red Bull KERS seems to be broken, I half wonder if they just aren't running it in any meaningful sense and have distributed the associated ballast in a more beneficial manner with some token functionality, rather than a proper system that would be more restrictive in terms of weight distribution :p
 
Forgetting they will start on softs and have to go onwards at some point. Someone do a spreadsheet, see what pirilli tyres need to do for distance wise,

Pirilli tyres don't seem to be affected by rubbering in. It's like 95% pure distance related and everyone is saying around 11 laps in the practice sessions.
 
Interesting tactics from Force India there. Kova at 15th, completely flattered by events, but still nice to see.
 
I'm not so surprised to see Kova beating the FI's on soft tyres vs hards, more surprised by seeing Maldonado in Q3 in 8th atm.
 
Massa's really living by the skin of his teeth, isn't he? Was 17th before he switched to softs, and then only 10th in Q2.

At 2 seconds a lap slower they're just not in the picture.

If we approach this in simple terms: Assume softs last 10 laps for ease of numbers, whether they last 8 laps or 12 won't make much difference to the overall result.

If hards last 20, that's 40s slower but saving a 21s stop, 19s behind.
If hards last 30, that's 60s slower but saving 42s stops, 18s behind.
If hards last 40, that's 80s slower but saving 63s stops, 17s behind.

You can see the pattern emerging, at that sort of 2s per lap deficit they'd need more than one race before you made up the difference over continually stopping for softs, never mind more than one round of stops.

When you add in the compulsory hard period, it makes the gap closer but you'd still be better off going for as much soft running as you can.

You're assuming that the softs run at full performance until lap 10 though. They don't.

Using your example, the hards are't two seconds slower for ten laps, then better. They gradually get equal to the softs in performance, then better them.
 
RBR have the front row nailed tbh, unless McLaren have something up their sleeve which I doubt.

I just hope it's Webber on pole.

As the softs drop off though, they'd be in for new, so the hards will never really outperform.

They're just not a viable option, merely something everyone needs to endure for the minimum time possible.
