Apparently they are running practice laps and qualifying starts at 7:50, heat races start at 8:00 and the A main starts at 8:40.
iRacing takes a bit of time and patience to get used to. I was the same way with seeming to spin every other lap, but you develop a feel for it. Quick demos like that are awesome but turn a lot of people away at the same time. I watch these Pro Invitational events and take heart in the fact that true pros struggle with this sim. I also get kind of frustrated watching the contact (especially last night at Bristol) and thinking "if this were a normal race, these guys have long since gotten the penalty or disqualification for 17X points." (those who iRace know what I mean. Even watching Byron lead and scrape wall I'm thinking "1X. 1X. 2X....")iRacing had an asphalt Bristol track simulator at the track in the fan carnival a couple years ago. I don't think I made more than 4 laps Bristol without spinning out!!! I can't imagine what this is like!
