Agree with Lewis here, if he comes in he'll lose positions, so better to gamble, if he suddenly starts losing a big chunk of lap-time he'll pit.
I wonder if Merc thought the tyres wouldn't make it so didn't give Lewis all the info so he would pit, as he refused to do so earlier?
Well...Merc dropped more points than they needed to, but they look in a fairly decent spot. Tough one to call from here on out.
