Need a hand making a grudge match fair....

Every year my brother and I throw down on the track. We live just north of New England Dragway in Epping NH and make it a point to drop in a few times a summer to baseline and then record improvements to our cars. It started 2 years ago with he in his '05 Chrysler 300C and myself in my T5 850 Wagon. The winner buys dinner. It's become a really fun thing we do and lots of family and friends come out to cheer us on and...well, bust balls.

Anyhow...with his 300C running 13.9's and my new auto-x car/DD a '98 GLX VR6 Jetta...we're changing it up a bit.

The first Annual Clayton Brothers Bi-crashathon.
Friday night at new England Dragway and Sunday with CMC autocrossing.

My question is this; Anyone know how I should score this? Just add all the times from the drags (maybe getting 3 or 4 runs), take the quickest run through the cones and then add the two...the brother with the lowest combined wins? How do you guys combine scores at the Challenge? Any tips would be greatly appreciated!

Ps...here are the last two flyers we did....

Why not keep it simple, take the fastest time from each add them together and lowest score wins.

Hmm..just comparing straight times might not work. How much faster do you think you'll be through the autox? Enough to erase the total from all the drag runs?

And someone please tell Margie, "..no, not that CMC!" before she has more flashbacks..

Add together the best run from each venue.

I would say (your drag time/faster drag time) + (your autox time/fastest time)

Lowest score wins. You could do it for the top two runs if you wanted to reduce any "flyers"... I'm a big normalization fan, so this will help reduce any differences in the scale of the difference (so to speak).

You could even do it over the top time of the day, which would reduce the effective difference (I think? I'd have to play with the numbers to see)

I like davidj's approach.

Awesome guys, thanks for the input!

yeah, you have to normalize in some fashion. Otherwise you are saying that one second difference on an autox course is the same as a one second difference at the drags. As a rough guess, there is (at least) 5 seconds of driver difference on the autox to 1 second at the drag. Even this assumes that the cars will be equal. That's for you guys to deal with.

If I was the autocrosser and wanted to win, then I would not normalize and stick with the "1 sec = 1 sec" comparison.

What about both drive both cars? Is this about the faster car or the faster driver?

In reply to glueguy:

OOOOH, very interesting!

I like the both drive thing.

This is a great idea! There's no need for "equivilency formulas" if you just make an equal number of drag & autocross passes in both cars! You can just go back to compiling total times. Of course, y'all might both start the "..it wasn't my car, and I wasn't used to it.." argument..

Our local club has two grudge match events each year. The way that it works out for us is you call someone out, and then you get your normal runs in your own car, and then after the event anyone grudging pays an extra 10 bucks and gets to compete in each others car. 3 runs.

But yeah, drive both. Its really the only way.

I like that!!!!

How do they tally stuff for the 2010 challenge etc? Is it based on event wins etc?

TOZ, there's a long thread containing rules & commentary upon them.

I haven't read it, so I don't know if the answers are in there, but it's probably worth a try..

This is copied and pasted from my local clubs forum on how their "official" grudge matches work, fwiw.

Details: For those that don't know how this works, two drivers pair up. You drive your own car for 3 runs and the quickest time counts. Then, you swap cars with your grudge partner and drive his/her car for 3 runs counting the quickest. You add your quickest time in each car together to get your total time. The person with the quickest combined time wins the grudge match.

As always, this is not set in stone. Lots of things can change and CCSCC reserves the right to change anything.

Let the grudging begin!!
