Walk in someone else's shoes? Try to understand why everyone is upset?
Adrian is windsurfing on a budget. To him, saying he has to spend $300+ often to replace a GPS that has questionable advantages but well documented disadvantages is offensive. Suddenly disallowing a device that he has used for many years, without any harm to the competition, does not seem to accomplish anything; it almost looks like a direct swipe at him.
Andrew has been speedsurfing at the highest level for decades. He has very closely experienced how important the introduction of accuracy estimates was for a valid results at the top end of the competition, where 0.1 knots sometimes make a difference. He has spend a lot of time looking at GPS accuracy and talking to people who know even more about it than he does. But his decisions are constantly questioned. Sometimes, it is by people to whom the question is new, for example because their approved device suddenly stopped working. More often, he hears the same arguments from the same people, who never acknowledge the validity of anything they disagree with.
Julien has spent a lot of his time to develop the best GPS for speedsurfing on the market. He keeps control of all possible aspects of the production so he can be sure the quality is there and he can honor warranties, rather than just outsourcing production for a quick buck. He has closely worked with the GPSTC to make sure the device works well for the competition, at times changing his decisions even against his personal opinions. Given demand, he could easily sell the Motion at twice the price and make more money, but he chooses to keep it as affordable as possible. But even though there is no way he can possibly meet the demand, he is accused of selfish reasons when he posts.
Everyone is pissed. Is that what we wanted? If not, can it change? Or can we remember that we all love windsurfing fast, albeit with different goals and constraints that can lead to different preferences?
As for the poll, responses have gone down to a trickle, so I'll disable new responses within the next day or two. I'll leave it open a little longer for anyone who has not yet gotten around to answering it.
Great post.
For the record, I am not questioning whether Julien's device is a great device for windsurfing. I am sure it is among the best. I am also not questioning whether having error data is useful for determining if bad data gave an inflated result. I am also not questioning that the data used for competitive results should be held to a high standard. I agree that if you are setting records and contributing to competition that the data should be the highest quality available (but I would probably draw the line differently to others here, as clearly some parameters like distance and NM are much less likely to benefit from bad data).
I do question the notion that unapproved data has no meaning that is presented by some here. It may the case for them. But if I use the same device all the time and see my results improving and I am careful to filter out data that is obviously incorrect, I see a lot of value in the data. One man's rubbish is another mans treasure. Any comments of mine above were not having a swipe at the accuracy of approved devices. They were just trying to establish that many users would be satisfied with +/- 1 knot accuracy and no error data if the compromise is a more reliable/convenient/cheaper device. For them 1 knot error matters little.
I do think that other than the obvious hurdle of the cost/effort of implementation, a two tier system addresses above allowing those who wish to be competitive to do so without being shafted by bad data and those who do it for social reasons to do so without having to deal with the negative of paying for, obtaining and maintaining an approved device. Such a system would encourage users who become competitive to get an approved device so they can be competitive. I like the graphic posted with data greyed out. But even just the (T) or (D) is enough to determine that with less effort. I do not agree with the 30kn 2S limit and 20kn alpha limit. The data is unapproved. It is not contributing to team results or public records. IMHO let someone monitor personal records... what harm does it have for others?
And yes, you are right. I used a legacy device for many years and all the bad data from it is already there in the database and filling all my PRs. My new device is probably better and I really just want to keep doing what I was doing competing against myself, but now the old device is out-ruled and the new device cannot be used. It would have been great to be able to compare results to older results but the current rules don't allow me to do that without spending lots of $$$ and then hoping it keeps working when I have a device on my wrist that does all I want from a device.
I am not sure where the poll sits at the moment. And I do agree that the results would be biased. But regardless of that, I think the Poll does show that a significant proportion of GPSTC users and potential GPSTC users support a two tier system. Probably not as high as 90% as the poll suggests, but surely even 30% makes it worthy of consideration?
