In case anyone is curious, I have found greater success in WHs recently, so thanks for all the tips. My WH trips are much shorter now, as I’m getting better at figuring which ones are more likely to have sites I can loot. I do keep stumbling upon holes with tons of recent explorer kills, and I’ve been erring on the side of caution. Basically, if there were a spat of kills in the last month, I just leave.
That being said, I’m probably being over cautious. I even say to myself “what are the odds that today, after no kills in a month, today is the day someone is cloaky camping?” But then I think about my Astero and the (sometimes) loaded up cargo bay and think, “nah, not worth it.” You know what, sometimes, it’s probably worth it.
In any case, thanks to everyone for making me a better explorer. Still tons to learn, but hey, progress!
