GPS speed is always inaccurate in short burst since it's purely time/distance with an error band that can go either way. No modern GPS is useful for timing. Creaky old GPS handhelds that used Doppler for speed measurement are the gold standard for speed tests, you might be able to find one on ebay for a few thousand bucks since no one makes a GPS Doppler timer anymore and the old ones are slowly dying despite the elaborate care anyone who has one lavishes on it. It's like Blackwing pencils which used to eBay for 40 bucks each for an unused one until someone bought the old factory and started making them again. Now they're a mere $2.50 each for suckers like me who love them.

Thanks B-W. It is odd. Later today after my original post i had a 55 minute foil session and my watch reading seemed accurate. I like your explanation of the watch registering top speed as result of a fast crash. Fortunately I was on foil the entire session and never wiped out either session. Maybe just a hiccup with the watch

Hey Caribsurf,
I recently got the watch and run it in kitesurf mode. Slightly different readouts than windsurf mode but I get the same glitch. I can't see it on the garmin website, but when I load up my session on my phone the graph shows what has happened.
Here you see the speed spike right before it goes to zero. I assume this is my body ragdolling across the water and accelerating the watch for a split second giving the false reading. A bit unfortunate that they track split second speed spikes, I'd like something that shows top speed held for 1-2 seconds for better accuracy. Other than that though, love the watch, especially the ability to track miles on my sails.

Interesting thread, I work for a small privately held company that designs and manufactures scientific instrumentation, and our President (73 years old) is all in on AI, VR + AR thinking that it is the future. I've worked with our service engineers on the VR + AR projects related to supporting our International Service centers and found this technology to be a huge benefit in diagnosing, troubleshooting and repair as long as one party involved is willing to sacrifice some sleep due to time differences between ASEA and Asia. We usually alternate on who has to be up at 6am or midnight local time so that the other can be available at 6pm or noon.
What I don't like is AI as I find it totally useless for my field and a huge time waster. Why does it waste my time? Our president insists on asking all different versions of Chat based AI questions related to our industry in an attempt to create marketing content showing our companies superiority of design compared to our competitors. What usually happens is that ChatGP give the opposite answer than what is expected, and I end up having to either prove ChatGP wrong, educate our president on the concepts that "words have meanings" and help him structure directed questions rather than vague questions. This can entail me having to write a several page responses with 1. the correct answer, and 2. a forensic search on where the incorrect information originated, (usually from a college science student blog, or a competitors marketing,
Personally, I don't use any AI since all information relevant to my role ensuring that our instrumention and software reporting conform to all national and international conventions such as ISO, ASTM, DIN,BAM, SAE, CIE, USP, NF, CP, JP, ANSI, ISEA, AOCS and about 100 other standards organizations, including the major publishers such as Wiley Inter-Science. All of these organizations tightly control their content behind firewalls, they have all added verbiage such as this; Artificial Intelligence Policy: ASTM International prohibits the entry of ASTM standards and related ASTM intellectual property (“ASTM IP”) into any form of Artificial Intelligence (AI) tools, such as ChatGPT. Additionally, creating derivatives of ASTM IP using AI is also prohibited without express written permission from ASTM’s President. In the case of such use, ASTM will suspend a licensee’s access to ASTM IP, and further legal action will be considered." to their websites.
What happens whenever our president uses Chat he gets bot answers that are only based on data from the public domain and zero input from the scientific community resulting in about 30% of answers being so incorrect as to be laughable., 30% to being circular nonsense and 40% to being marketing based responses.
Since I hope to 90% retire in the next year and earn a little money on the side writing technical papers for publication behind the firewall I hope to continue to earn some easy income factchecking AI answers for a few years longer. For laughs I may start my own blog and purposely post slightly misleading content just to have fun and see if it turns up in Chat GTP responses. Lol

I go back and forth on this question all the time. I am 63 my wife is 50 and we own a sales agency and rep different brands in the Caribbean. It's profitable, fun and every island trip a business expense, so I don't see me retiring for a few years but you never know. `

Last time I tried supfoil it was on a 6'6 x 30 board and paddling was not easy even though I am an experienced sup'er. Going to give it another go. Should I get a similar size board and work thru the problem or go for something longer maybe 7'6 for an easier time? I am 6' 185lbs but late 60's so not looking for anything radical, and not a narrow downwind board. Thanks

I'm a bit surprised anyone remembers that I was working on a book called the retirement trap. I barely did. I never finished it, it's got a lot of scratch pad stuff in it that I never developed or edited, and it's never been edited for style, brevity, accuracy or even decent grammar and spelling. But here you go: this link should work: https://www.ponostyle.com/wp-content/uploads/2024/04/The-Retirement-Trap-1663863538.pdf

ive noted that the number of surf suppers i see is stable, where numbers of surfers are continually growing -- lineups tighter and tighter, and sometimes gotta just mix with em bc they are everywhere (at my Brooklyn and RI breaks) -- makes it important to be on one's game -- supper makes an honest mistake, apology wont necessarily suffice
good is that the mass market sup surge seems to have reversed -- so there are fewer beginners on sups in lineups where they shouldnt be
there are hordes of beginners on logs, of course........but life's not fair

Good to see you back in game SA. I guess you are really enjoying that feeling of being back on the board and out in the water.
