Finding nine is more like luck then finding one. Note that just one of the nine (so far) is validated. If I tell you to roll a six on a dice and you do that’s pretty lucky. If I tell you to roll an even number (I.e., give you wider scope) and you do ... less amazing. They could have lab tested every compound in the set but it would have taken too long. The ML for them to 9. I’m not saying that this isn’t good work. Just addressing the statistical point re 1 v 9.
