Concerning 15km: I think this is fine. However be careful with a too short distance. There might be several problems:

- many waypoints
- it will take some time for convoys to arrange their formation again. Not enough time might confuse them too much
- the offset from the main course becomes smaller and smaller. For an zz angle of 25 degrees the distance is roughly 15km*sin(25). If this distance becomes too small you can easily position yourself just ahead of the contact and will end up in firing range.

I have choosen an angle of 25 degrees because cos(25) is roughly 0.9. Thus, the speed of the ship towards its destination is only 90% of the ship's sailing speed (increasing the time of the journey by a factor of about 1.1 and thus also increasing the danger). I don't think they sacrificed more speed for the pattern. I don't know whether it has any relevance, but if you look at the most simple pattern of the posted Japanese zz patterns you can also see an angle of 25 degrees.

Cheers, LGN1

Just another remark: the distance you specify is an upper limit! If you choose 15km you will see quite a few shorter 'legs'. Maybe down to less than 10km.
