Golden trees do not remain golden for very long. Duolingo tends to downgrade skill strength irrespective of your performance. I've got a tree where 'Basics1" is downgraded beyond repair.(...)
Does the dumbbell still use this method for reviews?
It may, though I'm not really sure it ever did. This could be verified on a tree where you let the skill strength decay on the complete first chapter. If you then get easy or trivial questions using the dumbbell, this would be a circumstantial indication that skill strength is indeed taken into account.
I have found an elaborate article on Greg's reflections treating this topic. Unfortuantely it dates back to before the introduction of the crowns, so the conclusions may no longer be valid.
