Scores for April 16 practise event at YYC
« on: April 16, 2017, 06:20:43 PM »
Morning only:

Afternoon only:

Best run of morning plus best run of afternoon:
  https://drive.google.com/open?id=0ByeFbiNdvLbGVWFiaHhJNElhb0E

Weather turned out much nicer than expected, and we got cars through fast enough to get 9 "official" runs each plus fun runs.

For those that wondered -- the new Miata is amazing at some things (turn-in specifically), but still transitions into some pretty bad understeer in mid corner.  Softer sway bar settings will be the next tuning item.

How is the 42.097 for my score calculated? Are cones worth two seconds? My time was 40.097+1.

That +1 is a cone that you hit and that adds 2 seconds to your time.

You're welcome!

But, yeah....just means +1 cone (or 1 cone penalty added to your run), +2 would be two cones etc. each 2 sec.   

DNF would be Did Not Finish ...

DNS is Did Not Start

DSQ - is Disqualified

Today was fun. My car is an animal that's going to take me some time to learn to drive it and some work to set it up to be fast.

Today was fantastic fun.  Interested to see what further we can squeeze out of our 100 hp red rocket!

Lots of runs this season see you in two weeks.

EDIT: I was wrong here. Disregard.

In other news, we're calculating cone penalties incorrectly in the indexed results. We're indexing the sum of the raw time and any cone penalties. I wasn't actually able to find a rule governing this, but the convention (as applied at Pros) is to index the raw time, *then* apply cone penalties.

Hey Murray.
Thanks for posting.
Am I not seeing where is is just classes ( I just wanted to see the results of just the HS class only) not sure if that's doable.
Thanks again for all you guys do!!!

This came a few years ago, and I can assert that PAX index has historically been applied to cones both in Canada (ASN) and in the U.S. (SCCA), at least with respect to autoslalom events (I know nothing about the Pros).

The first time we held the Canadian Nationals, I asked for clarification on this, and was told to index the cones.  This was done for both CAC events we held.

The most common software for autocross in SCCA is Axware, and it applies PAX to cones, with no option to do otherwise.
Example (with last year's version of Axware):
See car #31, class CS:
http://greatfallsracing.com/wp-content/uploads/2013/07/expo-4-10-16_fin.htm
His best raw time is 75.288+1, for a total raw time of 77.288

Now look at the same car's PAXed results:
http://greatfallsracing.com/wp-content/uploads/2013/07/expo-4-10-16_pax.htm
His PAX time is 77.288 x 0.819, for a PAX time of 63.298.  His cone penalty got PAXed.

I checked the timing data, and no such driver number ever had a run.

It's doable, but not easily -- I would need to re-group everyone and then re-score and re-publish.  We do not normally have enough cars in individual classes to be of any use, so we group them together (e.g. all street classes together in a STREET group).

It is easy enough for you to extract the results for just one class, since all of the results are order correctly.  e.g. William D placed first in HS, then Rob P, and so on down to Edwin C.

I checked the indexed results for a few of this year's national-level events, and you're right. I stand corrected!

BTW, this has caused some furious arguments in clubs, even since I have started.
CSCC decided to not PAX cones some time ago (https://cscc.speedracer.ca/forums/autoslalom-results/2008-autoslalom-results/msg36196/#msg36196), but then Axware came into general use and eliminated that option.

If we (as a club or clubs) decide to change how we do our calcs, it is certainly doable (and legal).  My scoring software has a config switch to allow scores either way (cones PAXed or not).  I made it an option because of these arguments :)
