Peter or Matt or somebody,

Peter showed me % time at full throttle, but I don't remember how to see that. Was that a VBOX thing or can I see it in Race Anaylsis as well?

You can use the histogram for that I think.

Matt Romanowski

Histograms are the easiest way to do it. For that, select the histogram button and then choose throttle position in the measures list.

The other way is to do a channel report and report the average throttle position for the lap.

ProCoach

The histogram is less effective for me. Roger outlined the math channels required to construct this shown on a strip chart last year. I'll see if I can dig it up, but it might be a few days.

It fits perfectly into Jorge Segers objective analysis tool to determine the efficacy of a setup change.

With drivers capable of turning laps within tenths or hundredths (that are close to the record or representative of a very high level of performance, not just driving to a comfort level), this is a VERY useful tool.

For those novice or intermediate drivers, it's a great comparison as to WHY and HOW they might be stuck!

ir_fuel

Are you talking about the throttle being stuck?

ProCoach

Haha! No.

Drivers can achieve more from a higher percentage of WOT (85% or more) than just about anything else.

You can screw around with line, braking technique, all kinds of other control inputs, but this measure, if improved, directly results in lower lap times.

That's it! Thank you!

Coat tailing this thread - I suspect there is a way to write a conditional statement to calculate the time spent at 100% throttle above a specific RPM (vs. time below this RPM), but I don't know how to do this.

Can someone help?

Cheers,

ProCoach

Sounds like you want to add "the Kibort condition."

Sorry. Can't help.

Seriously, none of the professional analysis of the "percentage of the lap distance at WOT" includes that modifier. Folks look at the histogram (and I look at a scatter plot of RPM vs Speed) to identify sub optimal RPM range use.

ir_fuel

I can understand his point though. If you are running 6th gear on the entire race track it would be quite easy to have 95% WOT

Matt Romanowski

It should just be a nested IF statements. If (RPM>whatever) and if (tps>95%), then integrate for time/distance.

I've always preferred to use a math channel since you can overlay it with the Ideal Speed, Corner Radius, Ideal Gear, and Combined G ("Gsum") math channels to paint a clearer view. YMMV.

Forgive, me for sounding snarky as I know that this will come across as such. That is not my intention. I am merely trying to point out that the discussion was about one relevant proven factor and introducing other suggestions to the discussion is, in my personal opinion, misleading.

So with that in mind here is my reply . . .

Yes, but ultimately for most folks asking questions here it's about getting on the podium in races. Someone driving 6th gear will never reach a podium. When you want to cut the final 1/10 off your laps, people like Peter have spent decades studying the data and whatever they tell you is important is most likely the best answer from a data stand point.

I'm not saying someone can't improve data analysis in the future because that would be silly to suggest, but I am saying there is a high hurdle of relevance to reach before one should be taken seriously.

% WOT appears to me to be a highly relevant data point, but not one that was easily uncovered hence the question. Asking something else is NOT a proven relevant factor.

Krokodil

Without understanding my background and why I am asking the question - how can you make this declarative statement?

My point on coat tailing the thread was that your question, which was already answered, involved the folks from whom I was requesting help - and there was no need to start yet another thread.

I am not sure why this upset you.

Cheers,
