This is the kind of thing I enjoy: Time-to-Emblem Ratios – Cold Comfort « Cold Comfort. I love seeing math applied to situations where it probably will never actually be used. (Maybe I should study economics.)
Anyhow, this is a calculation of how many emblems you can expect from a typical run of a heroic dungeon versus how much time it takes to run that dungeon. Thus, your best bet if you are collecting emblems is to chain-run Gundrak (at 2.8 minutes per emblem) and stay away from Pit of Saron (at 6 minutes per emblem).
An interesting point to note is how many of the instances have a minute per emblem number very close to 3. This indicates that Blizzard did a good job of balancing the time to reward ratio (emblem-wise) across instances. Realistically, run any dungeon and you’ll get roughly the same emblem rewards in the same amount of time.
