Headlight Adjustment Question

[TwistedD85]

When using the lights on the wall method of aiming should the most intense part of the low beams be aimed directly where my horizontal (headlight height) and vertical (headlight position) lines meet or should the beam be slightly down and to the right of where they intersect? I've seen both, but the latter makes more sense to me, so I don't blind oncoming drivers. And if both of those are wrong I'd appreciate the correct method, thanks

All I do is pull ten to fifteen feet from a wall on level ground and aim both lights in a slightly downward position. Once I have them both in the same height I aim the drivers light slightly to the right so it points more to the center and I keep the passenger pointing straight ahead.
