Thanks!
Dotible appraisal strength is indeed in 2-words and surpasses other tools in my opinion. The reason is simple, created by a domainer and therefore it "knows" how a domainer mind works.
The appraiser has helped me a lot through my domaining especially in early stages. Still using it. Results have been visible on NP for long.
Looking to improve it further though, and lately there have been lots of new developments, added single words, liquid names appraisal etc.
Edit: It's not perfect (no such tool is) but it's great at 2-word COMs and now also at 1-word modified domains.
