I've heard many complaints that units at Emporia are attacked within the first 3-15 minutes. But I also know some players, who send small squads choosing the Units with the highest capacity and lowest cost. Such squads don't spend much time on Emporia, so the risk to be attacked is smaller :)
While that is true, one must remember that type and number of units is in no way related to gathering speed, only the carrying capacity; the gathering speed is dictated exclusively by the Gravisca level, the 50% Oracle bonus at level 21 and a possibly active Gatherer boost of 25% or 50%.
A very simple example:
Let us assume we have determined (as you suggested above) that a 15 min. stay is a reasonably safe time frame before someone comes along and wipes out the troops. For an average player such as myself with a Gravisca level of 13, level 20 Oracle and no active gatherer boost, this means that ....
… I would send 30 Psilos which will require 15 min. to gather 390 resource units. Now remember that sending additional units is of no value since they won't gather more resources within the same time frame:
Subjectively, from experience, I would say 15 min. is already too high a value, but since units require 5 min. to get sorted before they can even be bothered to begin gathering, there isn't much leeway here. And choosing other units, 1 Mounted Peltast for 267 res in 12 min. Or 2 Thureos for 352 res in 13 min. does not really matter much. My argument is that these short expeditions require 15 min. of the player's attention and net around 300 to 400 res, which is about what I get when clicking on a tribute cart outside the city gates. I would even claim that I would put my time to better use by visiting my 200+ friends and cash in on all the tribute carts and boats.
One might of course argue that the above example uses low values for upgrades and bonuses as parameters and that upgrading Gravisca and Oracle, and activating the Gatherer Boost changes the equation, but even with all possible upgrades and boosters active, the results are disheartening:

With every possible boost, bonus and upgrade active, 200 Javs would bring back 2k resources in 15:00 min. (same for 100 Veles or Numidian Archers, or 10 Thorakites, or 7 Mounted Peltast). If I compare the no. of gathered resources and the high risk of units being slaughtered during their 15:00 min. stay, to sending out a bot raid which, even without scouting, will net 20k to 100k in the same 15 min., Emporia occupations seem, at least to me, not worth the effort unless the parameters are changed to make them at liest mildly attractive.
