Also, in case anyone is interested, I just finished doing a head to head test of different transport missions on ICS Alpha.
My 2 mining/indy/transport guys run transport together in squad. These stats are the money earned on 1 guy by having both guys run the same missions and doing all of them as squad assignments.
Both accounts are using diplomacy 5, basic parallel assignments 4, headhunter 3, logistics 1, navigation 9 (with t4 lightweight frames) and my corp has a 10% tax rate (which comes off the top, as most of you already know).
This is from doing the tier 1 assignment circuit (ics alpha -> asintec alpha -> truhold-markson alpha -> ics alpha) in sequers:
199550.25
32967
56943
---------------
289460.25 (1 run 2 guys, 10% taxes, per guy) about 12 minutes
This is from doing the tier 2/3 assignments (ics alpha -> galoly op -> berwelam op -> radholme op -> ics alpha):
114385.52
87412.52
41458.50
16233.75
--------------
259490.29 (1 run 2 guys, 10% taxes, per guy) about 30 minutes t2/t3 transport mixed
Relations are 17% on one guy, 14% on the other, so having more in basic parallel assignments, higher rep (for more mission access) and higher headhunter/logistics etc would make more money.
But it is clear that t1 pays far better than t2/3 does (more money in less than half the time).
None of these figures take the ammo rewards in to account.
Obviously, transport missions are boring and time consuming, in my opinion they should pay as well or even better than they do just for this reason.
Like other people I'd like to see player contracts for transport (this could easily be done by using the generic data console model so that people don't have their gear stolen/griefed).
