UKGPL Season 29 (2015-16) Historic Trophy (66) - Rouen - Dec 1

[Phil Thornton]

Sorry to Phil,

I drove over your wheel.
I was watching what you are doing and slided a bit too wide and missed my own Line.
It was quite a bit of space when GPL recognized a collision.

Later in the race, my engine exploded.

Hi Bastian
I submitted an incident report with a client replay.  Please do the same (if you have saved your reply - I hope you have).  Where there is warp involved the client replays are a big help to the moderator (although I'm the divisional moderator for this division I won't be moderating this incident, another moderator will do it).

Bad luck with the engine, I suspect this incident contributed to the engine damage.  Your car was a ball of flames on my client replay
Regards
Phil

.....with some of the closest racing (without contact, unbelieveably imo, in some cases  ) I've seen.......

The moderating team will mighty pleased to see that.  An easy race to moderate with some very happy drivers, it doesn't get any better

Hi Phil,  unfortunately i just watched it on the fly after my engine burn out.

Some thing i still don't understand. Due to connections difference and the age of this simulation,
everyone seems to drive his "own race" in a certain way - with slight difference to the master (server) which causes this warps and collisions that aren't collisions ?

Also, the clients seem to make their own decisions which are not correct. like phils gpl decided my engine to explode already at the crash and server did not ?

are these thoughts correct ?

Best Regards,
Bastian

Bastian, you allways race on your own GPL install, you use the physics of your PC.
Your PC gets the position of the opponent from the server 15 times per second,
if there is a lag in this info, your GPL will compute its position by itself for the next fraction of a second.
When it gets the correct next info the opponents car will do a sudden jump (warp) to its real position.
Big problem is if a driver looses contact to the server for more than some fractions...

Despite trying a car that I rarely use  ( the BRM ) and developing a setup during quali, I was reasonably happy with my pace. Well, I was for the first laps.

Then I started to push things a little, because I could see opportunities ahead. Ronnie was in a similar car and there were others tantalisingly just out of range.

That was when the weak point in my hastily contrived setup showed itself and the front tyres overheated. This gave me a very twitchy BRM at mid corner and I found myself wrestling with the over/under steer on the exits.
I even tried easing off for a few laps to try and bring temps back under control, but that all ended when the engine went very quiet. 

Grats to the quick guys and the podium. Nice to see a relatively clean race with a big grid  Let's keep it that way

[bagrupp]

thx for the detailed explanation.

Is my second thought also correct (engine failure)?

[Cookie]

Yes there can be 3 different interpretations of the result of a crash 
What really happened to your engine only your own GPL rpy tells,
the server gets a signal of a collision with an impact and handles the signal to Phils PC wich makes it's own interpretation

[bagrupp]

its curious somehow  great

There is a web page in the rules that describes warp and how warp can be considered a mitigating factor in apportioning blame in an incident.

My client replay of the incident is here.  I think you will find it is different to your replay .

Thanks Axel for the best explanation of "warp" I ever read
