Suffered through making video only to run out of memory.

This page brakes it down pretty well.
Please note that on the DATA page, all ETP calculations are correct except for "A/C to ETP" (bottom line) there seems to be a bug that's causing it. Not sure what it is i'll report it.

 

ETP location is pretty accurate.

what wind do I have to enter?

just from any waypoint before the ETP and one after the ETP or what?

Wind values you can take either from MCDU or ActiveSky and input them manually, I dont think those values matter much.

 

So lets say you're crossing atlantic. You initial diversion point will be CYQX and BIKF secondary (or LPLA depending on the track). Once you pass the ETP towards BIKF, change the values where initual becomes BIKF and secontary becomes EINN.
