Interesting. There are about 10 things which usually appear in hotspots for most ring types, so the chances of a matched triple should be about 1:100 and the chances of a matched triple of a specific thing should be about 1:1000.
- Borann (and the Beta Tritium triple) were extremely lucky finds
- There are a lot more triple hotspots in that region still to be discovered
- There is something about hotspot generation which makes matched hotspots more likely than random chance would suggest
I have not even seen a double Tritium hotspot yet. And I'm 'moving by mining', from hand to mouth policy. I have to take what I get on my journey, so a multifunctional miner (Vette) is what I'm using by now. All 4 methods might not always be the most efficient way, but certainly the most diversified one. I'm also not always in the luxury position to only pick non-rotation asteroids. This makes SSD mining in a Vette to a challenge sometimes. Before FCs I never was a fan of flying the big ships - I finally start to really love my Vette. As a deep space miner you don't need to make compromises in form of weapons: All weapon slots are free for mining equipment!
