Hmm, that's pretty much what the knp people say. Ie: suck it and see :-)

And 4 point is very easy, never had a problem with it.
You just follow the firmware method and it works every time.

And on my three point I've got two on the front level with each other and one in the middle at the back.
There must be better method, than just moving it around till it feels right.

Guess it could just be what you're used to.
