Nice video OP!
Out of curiosity, is there a strategy for optimum charge placement or is it just a case of placing bomblets and watching to see what the RNG-ish graph does?
My first go in beta I managed to crack open an asteroid with only four or so charges placed, while on the second 'roid I mined all but one fissure before detonation and it didn't even scratch it. In both cases the yield graph seemed only arbitrarily correlated with the effort I'd put in placing charges (although it did reflect the eventual outcome at detonation).
Am I missing a clue, or is there a large element of luck involved in this process?
What I do is I check every single fissure on the asteroid.
Fissures do have strength (low, average and high - it does say in the left bottom panel when you highlight them).
The seismic charge gun have three steps of charge (low, average and high).
So I simply fly around the asteroid, checking how many high and low fissures it has.
If it has quite a few high strength fissures, I start with them and apply the charge by holding the fire button till it's charged to the max. I usually fire two or three of them and check the graph on right. If the graph is slightly below optimal I apply one more low charge.
Try to stay within the blue bar (optimal) to get the best result.
Bear in mind, you can disarm the already applied charge from left hand panel (contacts). It does have a timer, though, so be careful.
