Zezo forum:

Hello,
Still learning but progressing, and really enjoying Zezo to get advices on the route to follow. Incredible work you are doing.

One thing I'm trying to do, and I don't know how to do it. (Tried to browse the forum but did not find it, neither in the FAQs)
Lets say I plan to be at fixed TWA 100 until 6pm. To find this 100 value I move the green curve (or the red line for straight trajectories) around my position to find the best TWA that aligns with the recommended red trajectory

Then, at 6pm, Zezo seems to recommend to choose another TWA: The curvature of the trajectory is changing. Problem : as the green curve is centered on my current position, I cannot rotate it around the 6pm position to find the best TWA after 6pm. Taking the TWA indicated at the 6pm point is not always ideal as it can change a bit on positions which are further. Is there a way to do this ? (Hope I'm clear)

I tried changing the start position to the 6pm position, but then the whole trajectory is changed...

The back dots have mouseover popups that show the TWA at that point.

There is also Chrome extension written by fellow user that parses the page and gives all the data in a table

Thanks for your quick answer. I will try this.

Pierre
Very interested in your response. I also have a lot of trouble with this.
Good winds

Hi,
Still struggling. For example, the green curve follows the trajectory until 1am, even if on each point the TWA is slightly different (but the green curve shows that in average 80 is OK)
Then after 1am it diverges. Every point seems to be around 90, but maybe with a few straight lines I could do something similar or better.
What I would like to do is move the green curve and the red line to any point on the trajectory to try some directions before setting programmations.
I think it is not possible... so what I do is stick a post it note on my monitor parallel to the direction I want to follow, then I move the red line parallel to the edge of the post it to measure the angle :-)
Of course this does not work for TWA / green line !
But with this for now I'm in the top 4000, so I'm OK, and very thankful to zezo and to post it notes!

What Cvetan said above. If you hover your cursor over the black dots it gives you the avg bearing and twa to the next dot. The track lines are only useful to the point where you have a significant change of path.

Also, there is a Chrome extension (route zezo.org) that works in conjunction with the router map that gives you a drop-down of all the adjustments in tabular form. One really useful item it gives you is cumulative bearing a twa. That is very useful if you just one to set a single bearing till you come back to the computer.
