That last five minutes of qualifying, I find I spend watching the timing screen, taking photos and preparing the qualifying groups. Switching to the computer to post in the thread is awkward as I use the same monitor and keyboard for the PS3 and computer.
Ideally, I'd like to see everyone who's going to race to be in the lounge at least 10 minutes before qualifying begins. If you've just sussed out the qualifying groups and suddenly get 3 new arrivals, that could really unbalance the groups. If you are in the timing screen, you won't see the new arrivals.
As a host, I'd feel really uncomfortable asking someone to leave the lounge, especially if there is 5 mins to qualifying starts and someone comes knocking on the door. If you know you're going to be late, PM the host otherwise I think it's fair that the slot is up for grabs.
Also, after last night's freeze, I'm convinced this was caused by me switching out to the XMB to read a PSN message. It froze when I returned to the game, so I'd be very reluctant to do this again.
Locking people down to certain race slots is a bit harsh, especially if a certain slot turns out to be less popular (say on 14th Feb

) By the looks of it, there were only 9 in the second session last night, so we shouldn't stop people taking part even if they have taken part in the first session. The whole ethos of this series is 'not too serious' but reading through today's posts we are in danger of becoming a bit too rigid with the rules.
I'd also count the persons best First race and best second race. Even if on diff nights. However winning the second race twice doesn't get two wins as points. Make sense?
The spreadsheet to calculate points is already comlicated enough - This would make it a nightmare. Plus as Blind says below, this would defeat the purpose of having the double-header event with reverse grid - The two races are seen as one big race.
