Note that there is a difference in price depending on whether the UA is marked as stolen or not. Somehow I got one which is not marked stolen and it's price is around 240k. I also have a couple that are marked stolen and their price is only around 180k, at the same station. So I think that 109 Virginis price is for a non-stolen UA and is not comparable to the others.
Here are the prices I have got so far:
Timocani/Pennington Station (orgin of UA): Stolen 181673, Non-stolen 242230.
LTT 12033/Thorne Port (15.31 Ly from origin): Stolen 181191, Non-stolen 241587.
Kali/Lerner Terminal (64.44 Ly from origin): Stolen 180316, Non-stolen 240421.
Looks to be dropping off slightly with distance from the origin for the UA, or it's dropping off in the distance I'm travelling for another reason.
OK, where the prices are the same, this means they should be equidistant to the original location. This means if our price theory holds up, it should be equally distant from Gatonese, Lati, LHS 3006 and Timocani. However, if these systems are already very close together (by the above ranges 15 and 50 LY), this means we have to put some really long distances in between to have better accuracy.
I did reach 109 Virginis yesterday evening with my exploration-fitted Asp and dropped into any SSS, USS and WSS I could find. I only had one encounter with three type 9 federal navy ships, but these did not fit our target description, no Anaconda support. It was overall not easy to hold up against some of the encounters, so I went and installed 6 Pulse Lasers and a 4D shield. I now have a jump range of 32 LY precisely and my plan is to make at least 3-4 jumps to get info on prices.
In my design of experiment I didn't account for that the UA are illegal and have to be sold at black markets. This will limit the choice of available outposts. Also I noted, that if you view the galactic map by population (just up the first notch) there is a sharp drop in inhabited systems near Peregrina. This means we should try to get some values in between and I would say around at least 100 LY spaced apart.
But first I have to get to work, experiments delayed until the evening.
