F1 2011 Monaco Race - Fuel Corrected Laptime Comparison (Vettel, Alonso, Button)

A quick visual comparison of the first three drivers' fuel corrected laptimes (about fuel corrected laptimes):



And in close up:



Here's the delta between fuel-corrected laptimes of VET, ALO and BUT compared to the current leader of the lap:

  1. Thanks.

    Please can you explain it more? what is the horizental and vertical lines?

    Thanks.

  2. @John In the top two graphs, the x-axis is lap number, the y-axis is fuel corrected laptime in seconds (as explained here: http://f1datajunkie.blogspot.com/2011/05/f1-2011-turkey-race-fuel-corrected.html )

    In the chart at the bottom, the x-axis is lap number and the y-axis is calculated according to:

    driver's laptime - raceleader's laptime

    If the line is above the x-axis, the leader had a faster laptime on that lap; if the line goes below the x-axis, the driver had a faster lap than the leader. If the driver is the leader, the line is on the x-axis (zero difference in time).

  3. Thanks.

    I am new to these Kind of graphs what do you mean by "Fuel corrected lap times" ?

    Thanks !

  4. @John - check out the post at:

    It explains the notion of fuel corrected laptimes, with illustrations. Main idea is that fuel has mass that slows the car down; as the car uses up fuel it goes faster (carrying less mass); fuel corrected times subtract the notional time penalty arising from lugging fuel around from the actual laptime.
