I just have got a hof on arkadia, I was dropping for ore and treasure with a f105 and got a hit with both for a total of 234ped, I dropped again same and got 2 more hits both size V and for the hell of it dropped again with all three types and got another 2 hits.
So that was 160 probes dropped in one spot for a total of about 247ped
So what's the most drops done in one spot and still returned ore by the rest of you guys???
