That would actually make very little difference regarding the speed of the game because I don't intend to run the races in a chunk, just that the updates would come in a big chunk for the teams. But you are right that the pace I had planned (1 race/week) is way too slow. Twice a week is a lot better so a season would last for 8-10 weeks.Plus it'll make the years move quicker, or it'll take ages to reach new years.
