Why it isnt like in the calendar (WS race)?
Some (including me) have already made the schedule around the pre-season calendar...
I only add the races there either after the previous race has ended, or in the case of back to back weekends, 2 weeks before the race.
This is to avoid people allocating for every race in the beginning of the year and then not showing up (like we see with one driver in WC).
