You are NOT stupid!... there are just so many small indicators and complicated systems to keep up with!... Don't get me wrong, I'm absolutely amazed by my Mavic every time I use it because I learn or see something new... it's like a Swiss watch with props!... but also complete with an almost overwhelming number of features, that work under so many variables and conditions... If I'm lucky, I might have the majority of systems memorized by the holidays!...
