Strange decay rates

I have been working over the past few weeks to keep my skill trees trees gold with daily practice, which usually seems to mean 3-5 revision exercises in a language each day. Last night all my trees were gold apart from the incomplete skills. However this evening I opened Duolingo and found that this would involve two French, seven Italian and FIFTEEN German exercises. Has something changed in the mysterious inner workings of the Duolingo algorithms that would have caused this?
