At this early stage, I think that the starting grid could be enormously different to the final result. I think this because the cars are thought to be extremely close, meaning that a spectacular/poor qualifying lap could put a car out of position, which will be corrected during the length of a race. In addition, the tyres are thought to be softer than Softy Walter so some might end up cocking up their strategy.
At this stage I'm thinking that P2 might be the critical session, as that's when high fuel running tends to be done.
It's unlikely I'll be offering a qualifying tip due to the timezone being awkward, and the pre-qualifying piece will probably be before P3 rather than after it.
