How long must we endure this nonsense from KA72 being posted to GPSTC?

ive never had a issue with ka 72 until the 5 of dec last year. 72 wont even open/upload my files.
yes im using a canmore gps all i can afford. some of us do this sailing on a shoe string budget.
ka72 cant or wont help with this issue. speedreader my computer needs a coffee update lol

I read all posts and James Farley and Dezza gets a thumbs up and also Decrepit's last post. TBwonder gets red thumbs, if we still had them. Although, I agree that accuracy is everything(at the competitive end), at least KA72 gives everyone access to files.

Yes it's good to raise/discuss the issue, I wasn't aware of that but will keep an eye on it from now on. I gave you a green thumb as well Maybe if any other examples are found they can be reported here. The idea of removing ka72 from posting takes away a lot of the gpstc sport and fun. Results without a back up file available or at least of pic of the tracks arent as interesting to read as there's no info on how the results were achieved. I'd say at lake George most of us spent more time viewing tracks on ka72 than the posts on gpstc

Well said, great work Dylan thanks for all you do.

I use more than one device because I fear getting a PB and then having a device fail. Mostly I've used a GW60 on the water and a MiniMotion for uploading through KA72. The difference has usually been about +-0.05. I suppose this backup has the advantage of also highlighting unexpected spikes, not that I've ever seen one.

Or play cricket with an oversized bat.

inclusiveness is not the same as democracy

I miss the GPSTC for the banter I could have in the comments with my team mates. I miss the motivation to go out with mates from my team for a good team result. I miss the profile page that had my data. My gripe at the time was that I did not change anything in the way I did what I did for many years on the GPSTC, but the GPSTC changed the rules and ruled me out. I could have purchased a watch that had the worst reviews of any electronic device I have ever seen because it usually broke within a year of use. I could have purchased a newer device that had stopped production of display devices due to most of them failing... but a fix to that was to remove the display and nobody could get them anyway due to limited production. Meanwhile I had a device that worked perfectly for me and was reliable over decades and had already significant data in the GPSTC database. I am no speed gun that was breaking records and only occasionally contributed to a team result and mostly for distance. I did not need the hassle to have a special unreliable device that would not give on water feedback unless I carried a second device and then had to manage two devices.

I was not the only one. A simple fix was available. The GPSTC already had a field to check that indicated if the data was positional or doppler which was supposed to indicate whether the speed data was "more accurate". This could be repurposed to indicate if the device was approved and therefore "more accurate" or unapproved. A web developer could have changed the calculations of team scores to remove the unapproved devices from calculated parameters that could be inaccurate (2S really is the only effected), and the team scores would not be effected by this "inaccuracy". Others viewing the data could see the data was from an unapproved device (without D near the data). I can't see how the accuracy nuts could be upset with this solution. Instead this was not done, and people are still posting inaccurate data via KA72 and other methods... so the GPSTC still has inaccurate data, but has been exclusive by telling sailors they need a highly limited range of poor quality devices in order to be part of it.

Someone on this forum started an online poll to see if the above solution was acceptable to the wider windsurfing community and the OVERWHELMING majority thought it was a great solution. I was shocked how little support there was for the GPSTC existing rules. Representatives from the GPSTC said that this would be implemented when it could be done, but in the meantime things would continue as is. That was several years ago and nothing has happened... except for the occasional mention of it by someone here that I am aware of. Perhaps the resources required to do the change are beyond the GPSTC... or perhaps they would rather just forget about it and remain exclusive. Perhaps they don't have the resources to change the inaccurate philosophy in the about section of the WEB page?

So now we have a situation that started this thread where data from approved devices is still getting errors into the GPSTC. This highlights the real problem to me with data accuracy. Regardless of the device, errors can get in. It is possible even with a track based device to look at the results and identify if an error is likely. 5X10S average even when there are errors will be much closer to actual as errors average out. For my sailing style and location I would always get a 2S that was 1-3knots above my 5X10S. If it was higher that that, I knew there was an error. I could inspect that data on a speed trace, and speeds should be smooth. If there was a spike this would confirm the data had an error and could be removed. To an even mildly experienced eye, just a glance at the numbers on GPSTC will indicate if an error is likely and could be investigated further.

At this point I don't expect anything to change. But I have nothing to lose by banging this drum, so I will continue banging when the opportunity arises.

Ive got a few of the latest mini motions just arrived if you'd like one Adrian, (or anyone else wanting to join a gpstc team, pm me), it would be great to see you get back into it for the banter and motivation with your team mates that you enjoyed before
