In the meantime, I have updated my matrix http://www.am-rennsport.com/HNR.html
Have you published this to places where there isn't as much SFI-hatred as in the IT community? I frequent a bunch of other forums and no one talks about this stuff like they do here. I also haven't seen this poll posted. I think if you want a good cross-section of the community, you need to go outside the world of IT.Quote:

Thanks for providing such a great service, Jim!
Very interesting to see such a disparity between "data from sled tests" and SFI approval.
Not sure how US-focused the participants were, but I'm surprised that so many would value the FIA cert. Good marketing? Since it is after all just a HANS quality control test, I mean.
- My pleasure..........Quote:

What does "head excustion cm" in the last collumn?
<duh>........ it means you found a sloppy typo on my part as it was in that last column!
Thanks for finding that........
Tom is referring to http://www.am-rennsport.com/HNR.html
That is Head Excursion in centimeters, data I have only found in the 2002 Melvin paper.
Not to mention "Ease of egress..." as the #1 consideration. Folks have figured this out, hence SFI's low rating.Quote:

The top 3 items people found "critical" were ease of egress, ease of driving and sled test data. The #4 most critical was that stupid SFI sticker! More than 1/3 of the respondents found that to be "critical". 1/3 or so of the market ain't buying without that sticker. At least, that is how I viewed "critical" when I took the survey.
If I was putting a device to market, I can either try to educate the masses about what the SFI is all about, try to promote another organization with a different approach (RSI) to the racers and the organizations, or I can say screw-it and make the best SFI approved device I can. Or I can do all three :)
Like I've mentioned on another forum. Jim, thanks for taking the time and effort. In addition to the work on this survey, for the data matrix and the moderation on the trackpedia forum.
When I look at every bit of raw data, and align the individual votes of users, I see that some people checked all 3 "approval" choices as critical. Maybe, just to be "safe"
Also, in the case of SFI, there is a chance that many checked that as critical in making a choice of what to buy but that doesn't mean critical in terms of performance. For example, if you race with an org that currently requires SFI, you might see that as critical to what you buy.
As this survey was broadcast across multiple message boards, you've got a cross section from multiple sanctioning bodys, and of those only the SCCA doesn't mandate SFI/FIA compliant devices. That is if you run even once a season with NASA, BMWCCA-CR, PCA, or any number of other sanctioning bodies, if there isn't a SFI sticker then there's no racing on the track. I say this not because I'm a fan of HANS or the SFI spec, because the wording of the SFI spec requires a device that crosses patent lines. For an example look at what's happening to Defender being sued for patent infringement. What might the outcome of this suite be? Is there a chance that Downing/Hubbard might loose the rights to future patent income because the also wrote the SFI spec?Quote:

Gotta keep the ad buyers happy.Quote:

And it is a cool chart.
Jim - You probably have ferreted all of this stuff out, but I stumbled on a small peice of data here:
http://www.racesuit.com/racesuit//ac...rd3/index.html
I hadn't seen that page, but I think I have that data.........
this continues to be revised

How about a survey question response to: Saves you from dying (or becoming a quadrapalegic) in a crash because you would have otherwise suffered a basal skull fracture ............................................... Level of importance? - 100% .......................
Jim,
What is "Quick Disconnect for Fixed Tethers" in column three? Apparently we sell them for $85-$95.
None of those results are published or otherwise verified.Quote:
