While driving 103 miles (each way) to my interview today, I got to thinking on this.
This line of thinking is primarily for my Vampurai, who can kill much faster and safer than my tamer (plus get away from reds).

This is for felluca white wyrm farming. The base source scales remain the same, but gathering is faster. I NEVER recommend anyone farming scales in Felluca destard, due to the champ spawn. This draws reds in flocks. Ice dungeon is relatively safer, but on some shards it is "policed" by red guilds.

Trammel / Ilshenar scale resources
Dragons: 7
WW: 8

Felluca scale resouces
dragons: 14
WW : 16

Time to kill one WW: 20 Seconds (timed over 60 kills)
WW killed in one minute : 3
SCales harvested/minute: 48
Scales per hour: 2880
Time to reach 80k: 27.788888888888 hours.

Figure roughly 34 hours, given time running from reds, resupply, the inevitable death, etc. Not bad really.
