Ha, nice one Frank. Richard loves bug-finders! He'll enjoy that one.
0.48 is the equivalent of a zero rating. We've always called this an
Assassin killer scoring project - not killers in general. As you can tell, SS is not so good at the bottom end and tends to squash them in pretty tight. Ruud's software method that he was working on with SumoCue (unreleased) was much more aimed at the lower end and spread those out much more.

An update here on any generalizations/observations/results would be very interesting, especially as I'm a regular lurker elsewhere (sadly not Frank's for a long while
).

Thanks! Richard has a long list of wish-list changes to SS(v3.0) (hidden killer triple, ALS cage block, killer quad etc) including many things for other formats, so the next V of scoring won't be for a good while.
Just to restate my last update -
SSscore(v3) is only reasonably accurate up to about 1.40. It will usually err on the lower side. This is because "easier" puzzles that have a long solution set the maximum at about 1.40.
Thanks for your interest.
Cheers
