Likely the time amount is meant to keep things simple on the schedule. Typical 30 minute race with a 10 minute qualifier is going to probably get a bit too close to the hour mark to let there be a race on the next hour.

And while I like the idea on paper of various levels of complexity ramping up throughout the different series, I typically can only race in 2, maybe 3 different series per season due to time constraints. Essentially, the complexity of the race isn't really a factor; I just race at the times when I can race (just before work, and after work on Monday and Tuesday, and weekends when I don't have other engagements).

I'm all for juggling the schedule a bit and starting to include races that start on the half or quarter hour to make room for some additional variation... but if the morning BMW races were 30 minutes instead of 20, I'd have to skip them as I'd be late for work. Like I am right now.

In closing, make more 20 minute races and less 1 hour races, so that I can race more often.
