I didn't say it was broken, I said it was stupid, why should having a few solds give any tom, dick or harry free NS's on you?
Does it get harder the less solds you have or is it equally easy until you have 0 solds? how is difficulty linked to solds/a?
Quite a vast proportion of the info is available now and we have open discussions about mechanics and I've asked bishop to check things with devs before.
This hasn't been "known" about, because it's still not known for certain, it definitely wasn't in clampys definitive article on NS formulae back on the old code.
