Here's the way I make sure I am at least in a good starting position to see the play developing: As the runner starts home, I put myself where I can see BOTH the runner and the base/plate in a direct line to one side of the catcher. In this case that means puting myself in a position where I can see them on the RIGHT side of the catcher because she started in foul territory. (This also allows you to determine possible obstruction better because you can see if the catcher "breaks" your line between the runner and the plate before receiving the ball.) To see both of them to the right of the catcher, you need to be approximately on 3b line extended. I'm not sure you nailed the call here either, especially since you could not see the actual tag. The fence view is not definitive in my opinion because it is hard to tell that the glove is actually touching the helmet or shoulder at the moment the video pauses. (It's also hard to tell if the fingers of her outstretched arm are touching the edge of the plate.)
