Nice speed!  Its a race to get to 20mph lol.  You should post the details of your fastest waves, rather than the session summary page.  If you tap on the 19.6 mph bar, it will give you a speed graph and gps track of that specific 'wave'.  That way we can see if your 19.6 was right before a big stack  ;D   You will also be able to see if you are sustaining high speeds or getting odd spikes.

Last year when I was riding with Ken Winner he was hitting 25 and sometimes 26 mph on a downwinder from Maliko in 18ft seas!

I'm curious what wingding speeds are.

I've seen as a much as a 5mph variation from garmin to gopro when wave foiling.

What's the method for verifying speed accuracy?  Or what's a proven accurate way to measure?

You have good reason to wonder. The only way to get accurate short interval speed information from a GPS is to find a GPS with doppler capability. That used to be relatively easy to find, but modern miniature GPS systems don't have it--they use a calculated speed based on distance differential over time. Given general location error band that yields an accuracy range of about +/-1mph at best and performance variations and conversion of a 3D location to 2D speed can make for pretty wild swings.

1) Can people please post Windspeeds with these wave speeds please.

2) The Dawn Patrol app shown above is using the iWatch (or maybe the iPhone) but has been pretty accurate.

I have been tracking wave speeds since 2015.  Almost every wave starting with the TRACE GPS (then the iWatch).  9,000+ waves.   The TRACE GPS recorded a GPS reading 5 times per second.  Typically it also recorded ~ 20% faster speeds than the RipCurl watches which were always slow. 

The TRACE and the iWatch have been nearly in perfect lock-step on speed which was a good sign.  The only downside I have found on the iWatch is that the distance is recorded Point to Point (for a single wave for example).  The turns, cutbacks and rare foil loop do not appear to add distance.  The algorithm may compensate for back and forth sailing but I have not tested.

Itís beginning to look like Iíll never break the 20 mph barrier with (Moses W1100) 2100 sq cm of front wing. I tired hard today. Crashed hard twice trying. Iím having a blast trying.

You sure are putting a lot of work into that!  Curious if youíre going just as fast to your weak side as your strong side? Iím always slower to my weak weak side, or maybe just less gutsy :P

I do ride about the same both ways. I can handle the same power and speed.

That said, Iím not doing speed runs weak side. Iím not crazy 😜

It's odd, but I think I'm faster on my weak side. I also get up on foil easier going goofy. I might be faster just because I have less control, or perhaps having less control makes it feel fast.
