Katzeye focus screen and K5 calibration

Hi,
My K5 is slightly front focus when using katzeye focus screen.
Can someone redirect me to the thread about how can i calibrate the focus screen by adding shims? If the thread does exist?
It's a kind of annoying when you see thing in focus, and later found out that you miss 1-2 inches.
The mis focus distance is depend on the distance to subject, lenses/focal length, and f stop. In other word, it is so difficult to get it right when using with wide/normal lenses at f1.8 and faster.

Thanks.

My common sense tells me that for front focus you will have to remove the shim already present in the camera and install a thinner one. How much thinner, this only you can tell.
