sure they have figures for last year ,but the question will be can you extrapolate those figures to what we will see in 2010? for sure this is not something linear ,why should it? we have heard anything from 4 to 5 seconds reduced performance over
a lap with full tank ,and one second difference would account for a lot more over a 60 lap race ,namely 0,08s per lap or 0,06s per lap ...assuming that we have the correct dropoff for a tanl filled up to what we saw in recent years ,I´d say those additional litres the cars will carry in the first two thirds now will hurt will hurt lap time really bad nothing close to a linearity...so in effect the weight alone of the fuelload is not the bad point ,as of course effects to tyre loads ,changes in rideheight-aero and CG height will not follow linearity.
