Scoring for Openings Trainer

Hello! I have been playing the openings trainer and I find it interesting that there are multiple moves required for a full score.

Perhaps it might be better to score the puzzle based on the correct answers instead of penalizing the ranking for one miss?

I agree & I too opined on this a month ago...
"I'm most curious how the "rating" aspect of opening training works, especially whether partial credit is awarded."

and Clarkey provided us some information:
"The scoring system is still being ironed out."

I'm hoping that in a month or two the openings trainer will get a significant amount of work done on it since the puzzles generator will be completed.
