Usually it was 2 - 5 second peak in yellow and the rest turning and gybing dips on our GC 300 meters long run.
Longer run on the lake Cootharabe recently and there is more yellow then waiting and dragging.
I wonder if you could share how proper 1 hour high speed graph may looks ?

You should check out one of B-Rads sessions

That is the point , I could not just check or download files. I could only wait for somebody to post.

Well here's my PB, from Lake George earlier this year, but it's only a 24.8




So these are roughly 2km runs.

And here's my 2nd best hr, (24.5) about 7 or 8km runs downwind but in chop.

Macroscien my best hours are also at Lake George, around 25.22 knot hour on 5.6m sail, large speed board. Top picture in the link, I was maxed....

There is no science to it. Seems high speed hours are a combination of flat water, the longer the better, planing gybes, the faster the better, and sailing with more pressure off your back foot for that hour (I myslef dont do that - I'm a lazy cruiser) and wind 20 knots plus. Best hours seem skewered to 90+ kg sailors.

Where we sail we have to do about 22 gypes each side for our hr

We do think, with a bit of experience, that the hr does require some thought

Sure the obvious, flat water, any state that maximises speed

but we are finding, an approach that reduces up wind sailing is the best

A flatter, more powered up cross, 10 to 30 degrees off, and 10 to 30 degrees up wind to maximise speed

sure you can go faster if you go further off the wind, but the upwind past 30 degrees starts becoming pretty slow

The adjustable outhaul plays a part if you want it do for sure

In my opinion, the real hr for competent gps sailors requires a different approach and rigging then sailing for a two sec peak

Great achievements Peter, Beside Google maps track it could be nice to see your speed graph for the hour.
Interesting to see is for me is : quality and stability of the straight run - which should be as flat as possible ( not up and downs bumpy like on my graph),

I wonder what is the average speed needed in your example to on this straight section to achieve 25 knots average. Looks like you have been doing 30 knots flat out !!! (NM 30.26 !! )

and efficiency of the turns ( gybes) short sharp dips ( not too deep ,which mean there are planing gybes most of the time - not like mines beach starts at the ends of the run )I guess that trying to achieve max 2 s speed during 1 hour could also compromise eventual result- as bearing off mean the we need to compensate with up wind slower sections.
Which means possibly the most symmetrical against will run in both directions - exactly 90 degree to the real wind.
Unless we have enough room to go and finish last few legs down the wind...
