Backsolving On COW build 69

[elirub]

I have followed the new video about back solving. It was showing a rating No (+169) following the candidate. I have done some back solving myself and could not see this rating (I have got the symbol rating though). I would appreciate if I would be informed about how it could be achieved. Further some results show a symbol rating of a CIRCLE what's that? and last what is the meaning of the settings in the Preferences concerning back solving.
Best Regards

Numbers are the numeric assessments of the leaf nodes which are assigned by chess engines. That can be done manually by visiting a leaf node, allowing the engine to think, and then grabbing the engine analysis. It is more commonly done by analyzing EPD files which is also known as "overnight analysis" because batches take a while.

A circle indicates that the best line of play from Backsolving is repeating the position. It is distinct form the equal sign (=) which could also mean equal chances for both sides.
