Hi Josh,
As Garina said, use PM or send me an e-mail at
elissen@eve-icsc.com - if you can please send me the details of the routes and attach the skillsheet XML from
http://myeve.eve-online.com/character/skilltree.aspAnd I tested fuel usage quite a lot before the patch that introduced Jump Freighters so if you have more details, like the Jumpplanner indicated 4567 isotopes, but I actually used 4789, would be very helpfull.
And to my knowledge, your position within a solarsystem does not matter. I investigated a problem once where I had a distance mismatch of a few au. Where I was in the system did not matter in regard to EVE letting me make the jump or not. But I'll try that one out as well.
