F1 » Tyre issues hurting Vettel pace

This is why F1 is a team sport. Without the car the team can't win. Without the driver the team can't win. It's a team effort through and through. Debating which driver can extract more from any given car is an endless debate even if they're beating their teammate on what's suppossed to be "equal kit".

F1 » Red Bull appeal rejected

@107SS2009: I fully agree a single sensor on the suction side of the injection pump should be the least error prone way of measuring the rate of fuel flow and integrate that into total fuel usage, however it would seem that something is interferring with the accuracy of the units, and some are suggesting there are measurable differences between supposedly calibrated units? Red Bull were never going to win the appeal as it was akin to ignoring a pit lane speeding dive through because you "know" you didn't speed and would argue it later. If the FIA knew during the race RBR peak fuel flow was too high (even if the sensor was known to be a bit dodgy) then they should have penalised RBR during the race.

F1 » Red Bull 'disappointed' by appeal failure

Busrider: If you get a speeding ticket from faulty radar or whatever, you will / should be let off. Same deal here i reckon
Yes, but the "crime" was not paying the speeding fine before the due date while waiting for thier day in court. Trouble is, they had to "pay the fine" during the race, argue it later, and there's no process to get the "fine" reimbursed. If they turned down the fuel flow during the race and dropped places, would the FIA be giving them back the places? I think not.

F1 » Red Bull appeal rejected

SAS2R:The data sheet provided by Gill Sensors (available on their web page) shows that 52% of their sensors have an accuracy of +/- 0.1% and that 92% have an accuracy of +/- 0.25%. I would hope that the sensors provided to the FIA were preselected from the +/- 0.1% bin.
Interesting reading. Their fuel flow sensor samples at 1khz, while you have 6 injectors firing once (?) every 2 revolutions @ ~12500 rpm which would equate to about 625 injections (fluctuatons in fuel flow) per second. Nyquist wouldn't be happy..

It's not hard for a team to figure out what's more accurate, the sensor or their injectors. Put x kg fuel in car, run car, weigh remaining fuel. A key point is that fuel flow may not be smooth and constant, you have multiple injectors firing over one hundred times a second and sometime during that mess of little fuel flow pulses, a sensor is going to sample the fuel flow back at the tank at a single instance of time, probably add that to a few other samples and take an average. There is clearly a technical difficulty that many of the teams are dealing with. In all sport, teams and individuals have to deal with bad calls from the Referee or Umpire and good sportsmanship should prevail. How the Ref should be punished for making a bad call is an ugly can of worms??

MotoGP » 'I wasn't thinking' says 'distracted' Lorenzo

@therealdave, with Carmelo in his back pocket, Rossi was going to get back onto a "competitive bike" no matter how bad his Ducati performance was going, Carmelo even said so publicly. If Stoners's first two years on the Duc were anything like Rossi's then he would have been out on his ear, not being offered a Factory Yamaha. Anyone whose worked in a large organisation with backroom politics fully understands how when you're the bosses golden boy you're on top of the world and magically things fall into place (Honda's tyre problems of 2012), but Lorenzo has demonstrated he's not the golden goose (revenue generator) that Rossi is,Sic was supposed to be, and Marques could be and now all his backroom support has disappeared and he's fighting a loosing battle.
