In general, I agree with the 3% rule, but think there should be a limit on an intermediate slope. For example, you can travel slightly uphill on the beginning of a run, peak the hill around 80 MPH, then have a -9% slope for the rest of the run and still come out to a net 3% slope and a valid run. But that -9% during the fastest part of the run will play a large role. This example was taken from a real-life case, and I have passed that information along to others wishing to set a world record. It seems to work very well. But maybe, just maybe there should be a limit on the intermediate slope encountered during the run.

The software at www.vboxtools.com was written with this in mind. There are both maximum limits and intermediate limits on the the verification. These limits are all documented at the bottom of your results when you submit a file to vboxtools.com. But since nobody could really agree on what the intermediate limit should be (in fact, nobody even agreed with me that such a limit should even exist), I set it to -10% for 60-130's which is pretty liberal and effectively disables the feature.

I also came up with an idea to "flatten" the road and normalize the results to a flat road. I actually have this feature programmed in, but disabled on vboxtools.com and perfdb.com (it's available on perfdb.org). I came up with the idea to normalize the results, just so we could take slope out of the equation. I passed my calculations to my physics buddies, and they agreed I was doing it the right way. Maybe, somebody would want to start a site/master list only using normalized results.

Since no such CRC exists on the VBO files, there is no CRC verification for them. You can tell which files a user submits because that is documented in the graphs generated where it says "File Type: DBN" etc. I can see from the graphs Costas has posted, he's always submitted DBN files.

If DBN files were hand crafted or manipulated, the user would need to regenerate the CRC for each line of the DBN file. The CRC used by racelogic is a bit of a ***** to figure out -- the DBN version is not defined as it's documented on their user forum for other devices. The DBN version is different that what they've documented. So anybody wanting to cheat would not only need to figure out the difference, but then figure out how to regenerate the CRC for each line of the file. Of course it can be done, but it's a lot of work.

I'm intentionally limiting my comments to the vbox device, file format, and explaining how vboxtools.com software is designed and operates. I hope this helps.

I was dead certain that you had something to do with prodigy's outrage and with wolfhedges attack (while you behaved in here quite good at the same time) as you now confirm... I do not see an entire community brought tgether to call out a fraud (a fraud that Dzenno definately has proven with his great posts above is most certainly attainable in this car)... I see 3000views in the thread and only 3 guys (2 of them are you and the other one misinformed by you obviously) attacking ME personally (like old times) and again bringing old grudges and insisting on childish arguments driven by sheer dislike/content/hate (I can not think of a better word) towards me personally!

Only members here who used to have M3's might remember your epic attacks not only towards me but towards Drew etc...

Anyway this is completely irrelevant to this PDK thread as I believe is your contribution to the thread since you do not own a 911 nor have you ever worked/vbox/driven a 997.2tt to come out as a specialist and give us your expert opinion on the matter!

I repeat whatever you say I will not reply to you again!

P.S. The story about me fiddling with the files at a software level is even more ridiculous than me running nitrous on a 997.2!!! Mike has the entire (start to finish period run (not only the 60-130mph part)) dbn file at his email and I welcome anyone to ask him if it is correct or not
