Aside from the timeline, as Wookie mentions, I think there are two other issues. One is that, as near as I can tell, Willis hasn't said that 4:1 is indefensible; they've only said that as a matter of business policy they've decided that only 2:1 is an acceptable insurance risk. The other is that (again as near as I can tell) Willis seems to maintain that the instructor followed the PADI standards. The consensus here may be that he didn't, but that's a matter for the real jury. I think that one of the few things everybody agrees on is that the defense is going to put the 4:1 standard on trial, and probably everything else that isn't spelled out in thorough detail.If Willis thought more than two was indefensible, why on earth are they trying to defend an instructor who not only exceeded common sense for the lake, but also broke standards at the same time. It's either indefensible or it's not.
Given PADI's expertise they should have been well aware that the new ratios would apply only as policies are renewed, so it shouldn't have been difficult for them to get the details right. That leads me to the conclusion that the best possible characterization is that the notice was careless. Beyond that, my perception is that PADI may be a bit too happy to uninsure their own members after the fact by claiming that standards were violated. The report by Horsnby specifically states that standards for direct supervision were violated when the adult separated from the group. Despite what some have said, I find it difficult to believe that it's a 100% certainty that it's possible to guarantee that none of the 4 people being supervised can get out of your control without you screwing up first. Dealing with any problem makes it impossible to devote the same level of attention to your remaining charges, but if one of them gets a bit too far away that's all the evidence required to establish that you've violated standards.Interesting that you didn't see it as PADI watching out for its members, ensuring they don't get caught short insurance-wise.
On a related note, I don't recall any specifics being mentioned about the point at which 4:1 needs to be reduced to maintain standards, but given the consensus that it should have been reduced at Bear Lake I'm sure there will be broad agreement on those specifics. If 4:1 is acceptable in warm, calm Caribbean water with 100' viz, at what point must the ratio be reduced to 3:1 or 2:1?
