Yeah I gave up the TPAC leg as I wanted more F legs so going back via the Atlantic gives me more time in the air. I'm also flying YYZ-IST with a friend so I am stuck in J for that one though I could probably find a YVR-MUC-IST in F leg if I wasn't staying on the same flight as him. I've still been wrestling with the idea of changing my return to ICN-LAX (
New OZ A380 First Suites). If I do though, I give up NH's F AND LH F plus the FCT in FRA so probably not worth it.
Congrats on CX F!!! Someday we need to have a beer, I dont know the first thing about accumulating non Staralliance points. What kind of plane do you fly for YVR-HKG-SIN?
As to the legend and the faded cities for the stopovers... I could tell you... but I'd have to kill you.
Spoiler!
Actually, Photoshop.

I created a composite image with a few different versions of the map which allowed me to create the dotted line, the legend, and fade the stopovers to 50%
