Greensmith has to show speed, a stage or even a split section would work.
Road position should help but it will be very hard. Then again in his case with own funding it's maybe not so critical.
As for Tidemand I warned already when the two starts were announced in January that I really hope he has a real program what to do after those two events... other than expect that some money will suddenly show up. So far it doesn't look like it.
