I know some guys who have done it, a mate from my school did it in that time frame flying monday-saturday 45h in 4 weeks during July/August, I tried myself this summer too but I was unlucky with the weather several days and not full availability of slots due to high season of time builders, I'll go for it in couple of weeks, secured 4h aircraft slot mon-fri for 2 weeks hopefully I won't have many cancellations and will be able to finish it.
