So do you aim for the actual overlap, or just target one of the two overlapping hotspots?
Just to add to the previous replies...
There's 2 different things you should think about.
Firstly, you want to arrive in an area where the hotspots overlap.
The game populates hotspots with appropriate 'roids so in an overlap there's two (or more) sets of appropriate 'roids occupying the same space and there's twice as many useful 'roids to shoot at.
Sometimes you can even recognise this happening, and you'll see patterns of 'roids repeated, offset from each other.
Secondly, once you've arrived in the overlap, you want to pick
something as a target to fly towards.
You don't want to just fly around randomly 'cos you'll end up going in circles and re-treading the same ground so it's best to pick something specific and fly toward it.
The hotspots are
thousands of miles wide so the hotspot POI, itself, is probably at least several hundred km away (cos you've arrived at the overlap between hotspots) so it's usually easiest to target the hotspot POI and fly toward it.
Alternatively, you can target the planet, itself, and fly toward that.
You'll probably only cover a couple of hundred km during a mining session so there's very little danger of you flying outside of the overlap between hotspots unless it's a really, really, tiny overlap - in which case you probably want to look for a site with a bigger overlap.
From what I've read, this only applies to laser-mining.
If you're planning on DC mining, apparently overlaps
don't yield a higher likelihood of finding DC 'roids.
This is just what I've read, though, rather than something I've verified for myself.
Also, the original criteria for finding a mining site still seem to apply. Ideally, you'll want to find overlapping hotspots in a ring with Pristine or, at least, Major reserves.
