Track experiments with RaceChrono

Kames - test day 31/08/14

Normal

Kames is a fabulous track located in East Ayrshire with some very technical skills needed to master it's curves. The normal direction is clockwise. The standard run is 2 1/2 laps and therefore you have to interpret the RaceChrono - tablular results to obtain a lap time that compares with a completion timing result.

* Split 1    Start - Hairpin 1
* Split 2    Hairpin 1 - Finish
* Split 3    Finish - Hairpin 2
* Split 4    Hairpin 2 - Start
A competition lap consists of  two complete laps + Split 2. In  the example below 34.24 + 33.45 + 12.8 = 80.49s

 You can relive the event by scrolling thru the data visually


Normal Track

 Reverse

This is exactly the same GPS data that I had previously blogged but I have rearranged the traps so I can more readily obtain a more comparable track time. This is done by treating it as 3 laps and subtracting off the excess data.

* Split 1      Start - Hairpin 1
* Split 2      Hairpin 1 - Finish Bend
* Split 3      Finish bend -  Paddock bend
* Split 4      Paddock bend - Start

 

This version of the track is 2 1/2 circuits also similarly interpreting the data 35.09 + 33.48 + 18.32 = 86.88s. Obviously I need to work on the normal direction.

Golspie - Kylestrome 09/07/14

 Golspie is a Kart track similar to Kames and again you need to arrange the split times so you can calculate a comparable event time.

* Split 1     Start - speed trap
* Split 2     speed trap - hairpin 1
* Split 3     hairpin 1 - Third corner
* Split 4     Third corner - Finish trap
* Split 5     Finish trap - Start


The direction this fine day was clockwise or Kilestrome format. Again to get a comparable time 49.76 + 39.14 = 88.90s

Forrestburn - track day 22/08/14

Forrestburn is my local track and is about 1/2 an hour away by van and trailer. I did an all day session on Sunday 22nd. For some reason after lunch I started a new session rather than continuing with the morning one so I have two sets of results.

* Split 1  Start - Hill Top
* Split 2 Hill Top - Hairpin 1
* Split 3 Hairpin 1 - Hairpin 2
* Split 4 Hairpin 2 - Finish

The results are just what appears on the tin and in this case the best lap was 53.5s second last lap of the day.

Conclusions

It is a pity the app is not more suited to sprint tracks where there are partial laps involved but with careful position of the split lines and some mental arithmetic a comparable result can be calculated. The convenience of a record of your results in your smart phone is a considerable advantage (I hope).
