I've been using Ancestry for a couple of months, and one thing I'm curious about is the 'tree ratings'. I understand it's a score to tell you how accurate your tree is likely to be, and I realise if you have more documentary evidence (birth certificates, death certificates, etc) it will improve your score; but what else? What is it based on? How would you improve the score? And how would you read the scores? What score is 'ok'? Good? Professional? What score would have you say 'this tree is made-up fantasy'? 😂 (My tree recently went from 8.4 to 8.5.) Lots of questions there! Thanks!
