I think it is fair to regard the Hel's system as a modern version of expert Acol even if they themselves would not. So 2007 for the BB but 2015 if you also include the Transnational Teams. What it proves is that most pairs in a position to win a world championship represent countries where Acol is almost never played. I could equally ask when the last time was that a pair playing Forcing Pass won a world championship and use that to argue that FP is a poor method. Similarly for Strong Diamond; or IMPrecision for that matter. I trust you would regard none of these as bad systems just because of their lack of representation amongst the US/Italian elite.
If you tweak a system sufficiently, it is no longer whatever name one gives the system on which it is based. Just as Meckwell or Meckwell lite are no longer Precision.
As for FP, I’m not sure it’s legal anymore. If it is, then I would argue that the fact that no good pair plays it shows that it’s a bad method. As I recall, when it did enjoy success, it was primarily through the lack of good counter-measures. The system ‘worked’ by exploiting its novelty, not because it has intrinsic merit. At least, such was my impression from reading various versions and reading the Bridge World tournament reports.
Same with Strong Diamond. Imo big diamond methods are inherently inferior to big club methods because of the seemingly modest but actually serious consumption of 1-level bidding space.
While my view is that high level competition is a true crucible that allows good methods to flourish and flawed methods to fall away, I’m am not usually a believer in arguments from authority. I’ve spent a lot of time on system design and theory. I’m no Kokish or Roswell, but I do try to judge methods by their use of space, ease of memory, and ability to handle numerous hand types. Obviously your views on any topic may differ from mine, and I respect that

Agree with AL78. Both partners were pessimistic. On a ♦ lead, you could try ♦QKA discarding a ♥, ♣KA, ruff a ♣, ruff a ♥, attempt to ruff a ♣.
