Sick, my I initial reaction is regarding qualifying length. 1 have run in several leagues on Pcars, and quali is at least 15 minutes, sometimes 20 at most tracks except Nord. Nordschleife in the DBR1 is a very long lap, and you need to complete 2 laps to get 1 quali time. Now that would mean absolute minimum of 15 min., but if one small thing goes wrong, even not your own fault, you will end up with no quali time at all...then you will fall to the back of the field. Remember on pcars the quali session ends when the time is up...no completing existing lap like in GT6. You can be 10 yards from the finish line, time ends, and the lap does not count!!
When you first leave the garage in quali, you will note the clock starts as you cross the finish line leaving pits, and that time is ok because your speed at Nord leaving pits is pretty much the same as a standing start on the track...however, if you need to zap back to your garage during that iNitial lap, when you go back out again The clock won't start until you complete that lap and cross finish line....
I really think if you want to run a race at Nord (which I very much support..best track in the game!) We should think in terms of longer overall session...perhaps 30 minute practice to get into the track and car mentally, 30 minute quali, 3 lap race.
As far as all other tracks, 10 minute practice, 20 minutes quali, then whatever laps you want.
I would very much suggest a 5 minute warm up session between quali and race...! leagues use this as a bathroom break, get some water, or just settle in before race starts..very helpful to us old folks .
As far as AI filling the field, interesting idea I have never seen done until last night when you and I were running the test races. The one thing I want to say is I wish that didnt have to be in our real races though, because it is very fun to be racing only against your human league mates...you can get into racing each other without extraneous AI cars getting in the way, or even causing accidents. Pcars AI is notorious for being overly aggressive at times...
Last point, you mention race results not staying there very long on screen...you can take a 'screen shot' right after the endof the race of the results screen by using the 'share' button on your wheel...push it and you will see option pop up to save screenshot. It will then be saved in your PSN profile page for as long as you want.
All this stuff is just my opinion/observation of course, so whatever you decide to do is okey dokey with me!!
