I do not know whether the FIA used such a delay, but I do know that several drivers probably had been jumping the start for their whole career! These guys kept getting a penalty (drive through the pits, the start is not aborted for everyone else) and studying the data showed a clear infringement in every case. I saw the data rather a lot since one of our drivers was one of the habitual start jumpers. He absolutely refused to accept that it wasn't his better reaction time for several races... The FIA guys showed me all the data showing considerable differences between the reaction times of the drivers, though I do not remember precise values. It is crucial to get the starts right so practicing it is very important...
