I've seen this discussed before, but I still don't understand it and I wonder if it needs a re-think?
I have finished the Gaelic tree and have all the crowns it's possible to get. I also have a "strength" of 90% and on past experience this is only going to get lower and there will be nothing I can do about it. I'm also recorded as having done 478 lessons out of 483 - but I have no way to find and do the missing five lessons. Similarly I'm recorded as having 3519 lexemes out of a possible 3525, and again no way to find the missing six lexemes.
There are 107 skills in the tree and according to Duome I am at 75% in 42 of them (and 100% in the rest). This will also go down (I mean the number which are at 75% will go up) and there is nothing I can do about it.
There was a point, about where I had finished the gold tree and was starting on the legendary crowns, that I had the skills that were only at 75% down to about half a dozen. At first I tried repeatedly practising these skills, but no matter how many times I did that, the 75% never changed. (Also they were all skills I was really good at already and practising them was boring, and took up time I could use better on skills I knew I wasn't so good at - some of which were showing 100%.) However, if I brought the skill to legendary then that did it - until it didn't. My overall strength went up to 99% at one point, but then it started dropping again. And every few days more skills dropped from 100% to 75%.
I stopped looking at the Duome page and concentrated on getting the skills to legendary, which I have now done. And 42 of them are showing only 75%.
I can understand showing statistics if there is some way for us to use these to improve our grasp of the language and winkle out parts of the course we still need practice on, but I question what use these figures are when someone with a legendary tree still seems to have things she hasn't covered, but she has no way to address that.
