and that he wanted to register the rare ratings for this game before it closed

ED=4.8/1.2/1.2 is not that rare, it's been played 158 times in the patterns games (1-442 inclusive).
ED=6.0/1.2/1.2 is also not that rare, it's been played 182 times in the patterns games (1-442 inclusive).

In this game #443 I have found 15000 solutions, but only 16 are present in the played rating list of the highest 78 submissions. The rest is worse

These numbers are low. For low clues puzzles in the Patterns Game, the number of valid puzzles number in the millions, the more clues the more millions.

Thanks 1to9only. I will examine the games. By the way, I produce millions, but about 1 to 2% survive and are submitted to PGExplainer. The rest is discarded because

• A Naked/Hidden Single in first move
• Has multiple same givens in band/stack
• Are the same as a previous attempt (minlex)
• Are not unique (none or multiple solutions)
• Are not minimal

All above can be user chosen by a checkbox.
I will add -5/+5 and -6/+6 vicinity search due to #169 and #381.
Maybe the choice of a next seed can improve much.
