interesting indeed. I was not aware that also for SER there was this morph dependency for high ratings. I wonder what you would do if a dedicated morph would be posted with an SER rating higher than the one of its canonical morph or its minlex morph.
I am still working on the list of derivatives, so I expect to have a new list in a few of days. Do you have an idea when the database that you are working on will be ready for uploading, and consequently until when new puzzles can be posted for inclusion?
As we discussed above, there is the potential for uniqueness techniques to affect the rating based on morph (say the two puzzles above have multiple 11.5 options at some step, and pick different ones because of the morph; one of these allows for a uniqueness technique, while the other permanently destroys that same uniqueness technique and must move to an 11.6 step eventually), or some shortcuts leading to not finding the absolute "shortest" (lowest node count) chain (this is more likely to be the case here, I would think - and this behavior shouldn't affect the rating more than 0.1 on its own).
It probably would make sense at some point to standardize rating to a single canonical form; in the case of a morph having a higher rating, it might be worth adding a column or two to account for that, not sure. Really, the lower rating would be the more "accurate" one (assuming no bug), since the higher rated morph can certainly be solved with the lower rating steps.
I could also generate a number of random morphs of each high rated puzzle and rate them to see which puzzles have this behavior, though that could take some time even on this computer.
As for the database, I still need to go through the pattern game so it will be a while longer. I'll keep adding new ones you find as you post them.
