I have also been seeing a lot of voting power depletions lately and I think it also has to do with the amount curation trails being done automatically. While this is a great strategy to support communities, I think it also hurts the user by not leveraging their influence and growth potential by engaging with the trail they support. I continue to prefer manual curation as I find more than enough content to support on a daily basis and have actually needed to lower my upvote percentages to adjust and throttle my own voting power daily. Thanks for the update!
