Re: Sorry, I still don't get it...
I'm not convinced that "software fault cost Mercedes the race" unless there VSC mode was imposing a greater limit than the rules required (which I find difficult to believe) so I think its more like "software fault meant Mercedes were surprised that Ferrari could stay ahead after tyre change" as it looks like there gap modelling failed to take account of the seeming loophole in the rules that meant the pit lane was nmot covered by the VSC speed limits.
