Translation as demanded:
You can think of a car/track combination to run after the "main event" on an evening, it´s been a thing for years now to sometimes have some more spontaneous events later into the night for those that couldn´t satisfy their racing needs beforehand.
So if you have a wish for something to race after the event at approx. 22:45 CEST, just tell us and we can make it happen.
Regarding the original question:
21:00 CEST has been the constant starting time for 12 years now as most people are done with dinner by that time and we finish early enough to still have time to shower and get to bed relatively early if you so wish or digest the race with a beer or two after.
Having it as late as your suggestion probably won´t fit well for other people here, but I hope you can still work your schedule to be able to race with us a decent amount (I sometimes have dinner during the practice session for example

).
