Previously, I could take part in 4, sometimes even 5 sprints within an hour. Now, with the current 10-minute time interval, it turns out that you either don't have time to prepare for the next sprint, or you're stuck waiting for it for 10 minutes, wasting time that could have been spent riding. With the current format, I barely manage to complete 3 sprints in an hour at best.
I think in this game mode, the goal is to ride as much as possible in the time you have. Why not reduce the interval between sprints to 5 minutes? They overlap a bit now anyway
