Here is the track from 3/11/18. The watch said just over 20 knot alpha and after uploaded to KA it was knocked back...sorry it was reduced to 19.634. Not sure if it was the same alpha but I'm pretty sure it was the same turn.
all I get is cesium, how do I download the file?

You download tracks from the "search " menu.

Sent you the link Mike.
OK,
Got it, and you're right it's the same gybe, but you went wide, so it's very short, only just got it into the watch's 300m.
so here's what it looks like with Real speed.
You can see the total distance is only 313.2m. because that's where trackpoints puts your 50m separation.
If you add another 3m and calculate for 53m
here's what you get.
So another 3m separation gives you an extra 43m total distance, lifting the average speed.
So I conclude from this that the watches doppler calculation of separation is an extra 3m here. So safest if you want to make sure of your alphas, aim for 47-48m not 50m

Hey thanks for checking it out.

It's really not a problem, having your own software can tell you a lot about what is happening, this case demonstrates that rather well.

Software analysis is very interesting. Again thankyou for your time and energy.
This case also demonstrates that the watch gave a higher alpha on the day than what KA gave and subsequently posted on gpstc.......hence my initial point that I made to Sue, that I noticed a difference on an alpha when she asked if any scores were 'knocked back' by KA.
Yes, but it could just as easily been the other way round, if the doppler track had been 3m inside the trackpoints, you may have got a full 500m 21kt alpha from KA72. and still had a 20 on the watch
Getting back to the topic of a broken arm band, if the strap breaks, then cut off other side and put inside your helmet, most helmets have hard form inside and it's very easy to just cut it out, my hard hat had Velcro inside and once watch is pushed inside the cut out then I stick the Velcro over the top, for the record, this is what I did when I first got my GW-52, I sold that as screen buttons where as much use as a chocolate fireplace, most people on her say the best place is on your head for clear path signal to the sky. I'll see if I still have a photo of the hat and GW-52 installed. Comments please ????????????????????
Yes, the best ting to do with a strapless GW60, I'm with you all the way here.
But most people also like on the water feed back, inside the helmet is a bit inconvenient.
And there's also the odd few that don't wear helmets, so it's not a universal solution. But it means there's a potential market, for a strapless watch.

You can buy one, but you will have to accept that the strap will probably break after a year or so (planned obsolescence?) I got 1.5 years out of mine, I now have a split halfway across the strap. Serial number is 168600702 which appears to be earlier than most of the others that have failed. Looks like Locosys don't care their name is going to be tarnished by a quality control fault. If they won't stand behind their product then I for one won't buy another one. My solution for now is to 3d print a flexible safety backing strap (printed with TPU plastic) that should stop me losing the watch when the other half of the strap does break. If anyone wants to do the same let me know and I can give you a copy of the 3d printer stl file I used.
Can you please share the stl file? 2 years after and still the same issue....
Bought a cheap rubber watch strap on line and attached using Gorilla Superglue. Had to shape using Dremel . So far , holding well ??
If someone could 3D print a cradle for a broken GW60 and have a two pin system that could use a Velcro band ... , I'd buy one.

You would have to find a fix for the dodgy buttons before I bought one
