14. Olivier Panis - 1'17"777 - lap 70
15. Mark Webber - 1'18"004 - lap 13
16. Jos Verstappen - 1'19"146 - lap 25
17. Justin Wilson - 1'19"169 - lap 19
18. Antonio Pizzonia - 1'19"437 - lap 8
19. Heinz-Harald Frentzen - no recorded time (accident, lap 1)

Except for Toyota's drivers, all the others were on same strategy.
Most of it is shown thruogh this statistic. But, Coulthard and Pizzonia????
Coulthard - almost a full second slower than Kimi?
Pizzonia - 1.4 on Webber?
I can understand this kind of things in quals, after all, it's only one try, and smallest slide can get you far behind. But race? In Monaco you have 78 attempts, and you get allmost or over a second behind your teammate?

Maybe this can say who is who in their teams, and Pizzonia really should worry about his future, while DC just mught consider retirement. I mean, I wouldn't keep a driver who is that slower in 'typical driver's' track, would you?
