Welcome to the Q&A Forum

Hi Trevor, Andrea from the Moz Help Team here Our Index rolled out yesterday and the blog post went live this morning, I'd recommend checking that out as well as the Q&A thread from Rand that it mentions which covers fluctuations (or non-fluctuations) with PA/DA scores. Hope that helps but we're available to assist if there are any other questions!

Hi there, Andrea from the Moz Help Team here, thank you for bringing this to our attention! I'm sending it up to our engineering team to take a look into this.
