Hello. I cannot find an explanation of how the "Strength Bars" work.
I was wondering what causes them to "diminish" so quickly? Even in less than 24 hours; I have lost strength bars from several categories. I had them completely full again when I worked last night, and then this morning there are already 2 that need topped-up (and they are two of the ones I just did last night ) Often, I spend hours "topping-up" my strength bars, and then have little time to move forward to the new material. Last week I had only one day of not logging in, and I lost strength bars in 10 categories (and again many of the categories I had just reviewed a day ago)!
Could you please explain what determines this? Thank-you. skv
See the comment of hughcparker in this discussion:
When many skills are un-gilded. Don't start with de first coloured skill in the tree, but with the last un-gilded skill. Many times you will see that more than one skill is going to be gold again.
Hi there! Duolingo tries to keep track of how well you know every word that it teaches you. The strength bars of the skills are based on how well it thinks you know the individual words in those skills. So individual words also have strength bars and these go down over time. See here for the technical details: http://making.duolingo.com/how-we-learn-how-you-learn
When there are enough words that it thinks you've forgotten, the skill's strength will go down and you have to practice it again. But when you strengthen a skill, you don't practice all the words in it, only the ones that have a low strength. The next day, the strength of some other words in the skill can drop down, and it will ask you to practice the same skill again.

Hello. Thank-you for the link. I do not understand what the "gilded tree" is referred to in the link. Does the comment just mean the "bars" around the subject lesson?
