Single skill strengths vs. overall strength?

I'm currently doing the Russian tree, and have noticed something that I haven't seen before. Every one of the skills that I've done thus far are golden, but the overall skill strength (beside 'strengthen skills') is only two bars. How is this possible?

Duolingo runs at least two measures of strength. The current strength - which is shown by whether or not the skills are golden, and the decay rate of the words - which mostly users see by how long it takes a skill to decay. It is possible that the overall skill strength represents a combination of these.
