The start times are more or less the same as what we have used in the RD iRacing Leagues earlier this year for the MX-5 and Star Mazda (which were run on Sundays). For me it means a 8PM start (UK time) when the server opens up. I could manage an hour earlier in the week, but any earlier and I'm screwed as would still be commuting home from work. So what works for some, doesn't work for others. I appreciate Pedro's situation so its probably something worth raising with Will/Kev and the RD iRacing League Admins before the new season schedules are posted, so we can get some feedback on best timeslots (especially when we are catering for folks from all over the globe).
Sunday's aren't usually an issue for me, so earlier starts in League races would be fine for me, but may hinder some of our US participants.
Regards the lack of no-shows for the recent EU midweek events, I think it was because Ramon posted them all well in advance of him going on his holidays and no-one was left to advertise them and rustle up some interest for participation and the posts just sat midway down the forum. There was also the fact that certain folks had signed up in advance and then never turned up, which doesn't help.
I also suggested having a minimum entry for midweek races put in place before someone goes and pays for a hosted session only to find no-one showing up. If a session guarantee say at least 6 or 8, then its worthwhile hosting a session, but should only 2 or 3 register, I don't think that's worth wasting someone's cash putting a session up. Just my opinion of course.
