What is consistence?

I was as the track last weekend practicing, and for the first time I was using a PT. First, I must say for someone who is trying to get better, the PT is the best tool out there. It really got me focused on how I was handling the track and gave me real feedback to my setup changes. For example, when I changed to my one way, even though it was harder to drive I bested my fasted lap with a diff by .5 seconds.

Anyhow, I know the key to fast driving is consistency, how far off should each lap be from one to the next to be considered consistent? My fastest lap was 13.2 seconds and slowest (without hitting a board) was about 15 seconds. Would a .5 second difference be consistent....a 1 second difference? Obviously driving in traffic and how much traffic makes a difference...

Consistency is like running 12.1, 12.1, 12.2, 12.3, 11.9.

Its not really a measure of how far from the other the times should be, its more of an overall measure.

I would not think that running 12.0, 12.5 , 12.5 12.0, 12.5, 12.0 would be very consistent, so I would say a max of 5 tenths from highest to lowest.

It really depends on you skill level and your goals. Even the best TC racers usually spread their laps over 3 to 4 tenths, maybe more...

OK...Right now I am only able to put together about 4-5 laps like that before a board jumps out in front of me

check out these times from the 07 euros. on the left of the page, scroll down to the A-mains. u can get lap by lap times. also check the other mains and see how the 'mortals' did. lol i try to get the laps in a 1 sec bracket. 23-24 sec at my track. never did it as yet be getting there. i think not crashing/hitting is the first step to getting consistent times.


keep trying!

Very cool! I looked at Marc Rheinard's best to worst time was about .5 seconds difference and he is a world class driver. I look at the O main and those time ranged within 2.5 seconds from best to worst lap. Interesting

we just got alycat software and here is a sample result. You will notice the term "CON"... this is the consistancy factor, it is the average of the best and worst laps combined. The lower the number the closer the laps where to each other, it does not nessarily mean it was the fastest car but it was most consistant,but as we all know tyically fast guys are more consistant:

Name Laps Time Avg Best Cons Comments
Gordie 28 5m 9.494s 11.142 10.815 0.29 Track Record
Jonathan 27 5m 2.717s 11.299 10.882 0.35 Personal Best
Matthieu 26 5m 6.973s 11.910 11.052 1.19

Hope the formating transfers ok.

So on average Gordie ran withing .29 seconds lap to lap, while Matthiew was 1.19 from lap to lap.

Worst CON of the day was 2.6seconds. and best con was .17seconds. Do more laps and make less mistaks and your CON improves.

I aim for less than half a second difference between my fastest and average lap over 5 mins

You need to factor in the size of the track or the number of turns as well. How much grip the track has would also be somewhat of a factor. For instance, a track with 8 - 9 second laps you'd probably want to be within 1 - 2 tenths a lap. However, a track with 15 - 20 second laps being within .5 a lap would be about the same as .1 - .2 on a 8 second lap track just because of the difference in number of turns.

Also, it "should" be easier to be more consistant on a high bite carpet track vs. a lower bite outdoor asphault track.

Just remember, the smaller tracks a tenth will make a bigger difference than on a larger track. You should always shoot for the same laptimes every lap no matter what size track or conditions even though you may never achieve it. The closer you are to hitting the same lap each time the better your overall run will be

i realise that we mortals compare ourselfs to the top drivers, but i think it hides how good we really are. im pretty sure if we could practice 4 times a week with 10 packs a day wee would improve greatly. like u said the O main range was 2.5. and thats pretty mortal. lol cause i think those times in the A main are superhuman lol.

I'll just echo a couple of things that have been said above really.

Personally I rate a very good run as one where my average lap is within .5 seconds of my fastest lap. I am a good club driver, no more.

Even if you look at the world class drivers they will be 0.3s gap at best, that's why checking results of big races is worth doing, the gap in consistency between a good club driver and the world champion is not that much.

If your average is more like 1 second off your best then you have a little work to do still, you must be missing apexes and having wobbles pretty regularly.

Another I'll say about consistency is try to run a car set up that lets you be consistent, and practice with that.

A car with a shade of understeer, and slightly underpowered will be easier to keep consistent over the 5 minutes, a looser, faster car may run a quicker single lap but it will be harder to go 5 minutes without errors.

In stock you usually need to be hugging the apexs as tight as possible and getting as much drive as you can out the corners. The earlier you can get the power down the earlier it will equate to some speed

As with others, I'd consider a good run being all laps within 0.5 seconds of each other
