Well - as per usual definition three white/three red should normally show if the deviation from the glide path exceeds 0.17 degrees, and four white or red at a deviation greater than 0.5 degrees. Thus - a dot on the glide slope equals (assuming PAPI and GS transmitter are colocated and aligned, and set for a 3 degree path) four red or four white.
Then again none of this is secret knowledge, and can be found within seconds with a Google search...
