I had that same reticle in a 5 Series 3-24. For me, it was aweful. There is a center aiming dot. It's the upper most dot. The upper tips of all the dashes that go cross the horizontal is your zero line. The bottom of the hash is .2 down. Also, in the 3-24 at least, at minimum magnification, the tree didn't extend nearly as far as the pictures show. Not my shitty picture but this is what it looks like at 3x to give you an idea of size of reticle.
all the other little things I could have lived with. That reticle tho.
