Definitely a good thing that PD is listening and responding to the players. I was on the same boat as most here, feeling that rotating races on a weekly basis was a bit too long, but I do agree with a daily cycle being too quick. I for example have work, and need to tend to my daughter, so it often only leaves me with a couple of hours of free time in the evening, before I need to sleep and do the cycle all over. So in that span of couple of hours I need to practice the track, fiddle with the car's setup, even try different cars to find the one best suited for me for that particular track to try to maximize my efforts .. it's just too short for a normal weekday, and I highly suspect many others feel the same.
In my opinion, a cycle of maybe 3 days would be brilliant, that gives around 2 cycles per week.
