* 2009-09-05 Connections skill bonus was removed from all agents who have no personal standings towards the character (all of RnD agents). It is in the patch notes, somewhere. Use this options to calc with old mode (not recommended).
** 2012-10-29 There was some changes that descibed in this devblog:
Profitability of all the R&D Agents was decreased twice
The 10 000 ISK fee was introduced for each datacore
The columns "ISK/day" and "ISK/month" take account of these changes, so the total profit, that is displaying in these columns is decreased by 10 000 ISK per datacore
The profitability of the R&D agents is evaluated among all the agents accessible by your character (based on the skills specified above). Thus, if the 1st agent in the table is ranked 3, it means that there are 2 more profitable agents among the corporations which have not been selected. Recalculation of the ranks is made after the prices are updated on the datacores. The prices are loaded in an automatic mode twice a week through API eve-central.com. The floor price of sale orders in Jita is used.
