TCN Yardstick - questions for the experts

[Mistermann]

Yesterday @Casmo released this video where he and Natso chat a bit while they go through startup, taxi and takeoff.  There was one moment in the video in particular that I have some questions - it dealt with the yardstick element.  I searched the manual for the word "yardstick" but nothing was found.  Figured I'd ask here to see what people say.  Below is a link to the moment in question.

Natso's jet is set at 69X and he tells Casmo to set his jet to 6X.  A comment on YT said to make sure the jets were 63 channels apart.  I fly with a few other fellas and am wondering if this yardstick element only works in 2-ship flights.  For instance, say I am flying with 2 other people.  Is there a way to configure this across all 3 jets?  Is this simply a way for 2 pilots to know the distance between their 2 jets just by looking at the HUD?

Any links to yardstick doctrine or simple "this is how we use it" (especially in DCS) are greatly appreciated.

So you can use it with more than two people but if you have 1 person on the low number and 2 on the high number, the person on the low number will only see the distance to the closer high number. I use yardstick all the time with the group I fly with to do "Tacform" it allows us to fly 1 or more miles away from each other in formation to help with mutual support. I wrote a guide on it a little while ago https://docs.google.com/document/d/1AknC14Sz25ZFD70En1WuM7p3FFIHP2rvqIeisFWsslk/edit?usp=sharing

The main thing here is if you are on a multiplayer server, don't use anything below 37 and 100, it will mess up the datalink for everyone.
