  5. Algorithms and Staying Gold


Algorithms and Staying Gold

Anybody have particular strategies for skills staying gold for longer? I finished my French tree gold, while going through the tree slow and mostly only letting myself take on new skills when all the others are still gilded. I've regilded it a couple times since if memory serves, but still a week can go by and it already shows 35 more skills I need to practice. Not sure how the algorithms work but I think trees in other languages seem to stay gold longer? but maybe that is just my experience. I tend to like the timed practice, but maybe I should do more untimed? If I kept on a skill after it was gold would it stay longer? Do algorithms not change at all with % fluency?

I like to keep everything gold. I agree with Actiregularis that finishing without mistakes seems to keep them gold longer. I also discovered that continually reviewing the final twenty skills seems to keep the entire tree gold -- probably because all skills and most vocabulary appear in the advanced skills.

After 60%, it takes a lot of work to add percentage points, doesn't it. it took me ten days to move from 67% to 68%.

  1. This is my favourite method

  2. Duolingo's web version (www.duolingo.com) strengthens much better than the App


Not sure how the algorithms work ......



I had read from someone in another thread, that the app handles the strengthen of weak words better? :)


Not in my account in the Android App.

You can easely test it in your own account both in the Web version and in "Android on Bluestacks":

  • by strengthen a skill and count the words, which are strengthened in the "Words tab"

In one strengthening in the web version, my "Words tab" showes up to 4 times more strengthened words than in the Android App.

Maybe, it depends of the A/B testing in our accounts.


I usually do one French "strengthening" every day (occasionally I do more), and I find my French tree is almost always entirely gold. When I first finished the tree I had a lot to do, though. Give it time and it should be fine...


I find if I do several timed practices in a row with few errors (and few hints), then a skill will stay gilded for quite some time indeed. That said, this is something that is subject to a whole lot of A/B testing it seems, which I think makes people's experiences differ more than we might expect.


Here is an interesting post a linguist posted a couple of years ago https://www.duolingo.com/comment/6176795/Best-Way-to-Make-Your-Tree-Turn-Gold-and-Stay-Gold Bonne chance!


Great question, sorry I cannot help! (have a lingot! ; )


My feeling (I have certainly not made any notes on what skills have been golden and when) is that skills that I have tested out stay golden much easier than skills that I have learnt.
