I found this puzzle and 649 of your list (including the first 11) in my collection of 4.5 mio "step 1" 22 clues, but never rated them.
Note the poor q2 ratings of some puzzles in your list, e.g. your puzzle #625 (ER 11.1) has q2 412 - like a simple newspaper puzzle.
So it's not really a new one. As you are a native English speaker, I let you find a name for it.
Regarding the filters, it's very simple. I use now the SE clone skfr.
It's working properly up to the area 10.5 _ 11 with a speed ratio exceeding 1 : 100 in the upper field.
I worked exclusively with skfr in the game 146 and got some rating equalling SE rating +-0.2 for ratings over 10.
As you likely know, it's not yet an operational program, but if you want to test it, you can get a copy of the code (or you can join the team to help developing).
My target is to give up as soon as possible the SE rating and to replace it by skfr rating, but I have still 3 steps to implement and many tests to achieve.
The team will restart the work after the holidays period.
