to be honest the problem isn't the tests run its the number of cars taking part

35 cars = 105 tests needed per race x 3 = 315 tests. so we have enough cpu time to run 315 tests.
10 cars = 30 tests needed per race. 315 / 30 = 10.5
with 10 teams we could of had 10 races and still use less cpu time

or 15 teams = 7 races

don't get me wrong i'm not taking anything away from the effort etc from nick and julien. but i think i've shown you could compromise and have 10-15 teams and still have a decent number of races

Fewer cars?? How do you decide who can join and who can't??

I understand, but we have the problem of the number of race available and we can partially solve it sacrificing like less than 1% of the accuracy... why not?
Anyway i don't want to insist too much since it's not such an issue. It just seemed to me like the easiest solution.

by my estimation doing what your suggesting will only get 1 extra race. its a solution in a way which unfortunately will take away a slight amount of credibility from the championship in that it will loose some accuracy. and open the door to people complaining that there car is doing crap because its not tested at 3deg

indeed, but of course i'm not suggesting that for the incoming race, which starts like tomorrow. Maybe from the next season.
And about the accuracy, well, it would be nice to have a reliable estimation. If it's something, as i think, very small, it wouldn't really compromise the credibility of the championship.

when i say less cars i mean 1st come 1st serve when it was announced this championship was going to start - its obviously too late now

we just might be in a position where the championship is won after 2 races which would make the 3rd race pointless

It would get a bit comical in my opinion: there wouldn't be any trace of meritocracy. ok, the champion might be automatically registered, but the other entrants would just be the first to notice the "start of the new season announcement" and have an internet connection available. And of course A LOT of people would be excluded to make that effective.

I think its a bad idea to limit the entrants to such a small number, if there were only 10 teams then there would have been no Variante, RicMe85 and many other teams. I don't see how this is very fair or very effective for the sponsors. I would be very suprised if KVRC had to limit teams as I suspect as many teams will leave as will join keeping the number at a perfectly reasonable level. I know the more races the better but I think its much fairer to have 40 teams, and 3 races than 10 teams and 9/10 races.

you've just quoted me in something and yet not taken any notice of what it said.

. I'm taking back in October or whatever. I'm not sure at whats comical in saying we are going to have a championship of 15 teams entrants on a 1st come 1st serve basis. it happens with everything in life.

i was using 10 and 15 as an example of trade off between entrants and amount of races we could have

it depends what view the sponsors have i guess

If the championship is limited by cpu time then the championship should be set up accordingly to ensure there is a fine balance. In an ideal word there would be no limit and we could have 35-40 cars and 10 or so races.

anyway i'm not here to argue i'm just simply making examples of how we could of had more races.

Im finding some of the response truly BIZARRE.

Why wouldnt we have those teams if the entrants were limited?

What is comical about limiting entrants? Most competitions will have a limit for one reason or another eg judging time, time to schedule races/matches/whatever, cost, the list goes on.

How is a contest better with more entrants and less rounds compared to less entrants and more rounds? Surely having more rounds brings in more variables which in turn will bring in more competition? As it stands there is little point working on the cars between races whereas with more rounds you can make modifications between rounds to try and gain valuable laptime in the hope of creeping up the scoreboard, with so few rounds the championship will probably be 75% pencilled after the first race with little change thereafter.

With comical i mean this: i'm waiting for the KVRC season's start to be announced; i am spending a 1 week holiday on the Alps and thus i barely have an internet connection (well, i don't even care about the internet when i'm on holiday); during that week the hypothetical KVRC announcement comes out; in few days the max n° of entrants is topped; when i come back home i realize i'm out of the KVRC season. Now that's (sadly) comical.

I think Ive already mentioned this but it bears mentioning again: The supplied tub file (at least the latest one that I have) has a wheelbase of 3450mm. I've moved the front wheels rearwards by 50mm on my car, which makes the wheelbase 3400mm as demanded by the KVRC rules. With the wheels moved everything lines up correctly with the way I've drawn out the regulation boxes, except for the floor leading edge being 50mm too far forward on the supplied tub, but its obviously too late to change that.

What a load of bollocks.
Thats the way of life, if yor lucky enough to be on holiday then expect to miss out on things or plan something to cover the possibility of an announcement whilst your away.
Its like asking the organisers of the London Marathon to open the entrants up to an infinite amount just incase you are unable to register from the start and possibly miss out on a slot.

You seem to forget that we do have another option: let everybody race with fewer races available. So it's not how life is but it's how we want it to be.

BTW cdsavage's post is important. I hope it doesn't fall in the "oblivion" of messages and gets an answer soon.
