So that's 18 then. And no: we're piloting the bartering phase this time so I wanted to make sure there was plenty of time in the process to give it chance. If it works then we might shorten the timescales next time.
Didn't the same thing happen for the Monaco sweepstakes? The way that'll work is that you need to agree with whoever has Vettel and then both post: who you want to swap with which driver you're giving away which driver you want in return. If it works then this will give the added dimension of making a prediction but will also ensure all the drivers are picked (i.e. everyone doesn't just choose Vettel). Because of the tiers, whoever has (e.g.) Schumacher might think he'll get beaten by Rosberg in Tier 2 but might think Webber has a chance of winning Tier 1, whereas whoever has Webber might think Schumacher has a shot at coming top of Tier 2 but Webber has no chance in Tier 1, so both parties might be amenable to swapping their drivers. If it doesn't work it'll be a complete mess and we'll never try it again.
