				If my creaky old brain is still working properly, your overall percentage reflected light for any surface can be calculated thus:
((R+G+B)/765)*(Diffuse+Reflection)
Where:
R = red component of colour channel (0-255)
G = green ditto
B = blue ditto
Diffuse = diffuse channel in %
Reflection = reflection channel in %
Your result should always be less than 100%.
Probably q. easy to set up a spreadsheet to do the calculation for you when you need it.
If this is wrong, I'm sure someone will point it out.

				if I multiply the sume and division of the color cannel with the  sume of difusse and reflection,.. i will fas allways get values more than 100%

				Eh? The (R+G+B)/765 part can only have a result between 0 and 1, so if you're getting an overall result greater than 100, it means (Diffuse+Reflection) must be greater than 100. So, you need to reduce either Diffuse or Reflection (or both).

sorry I could not look at your scene last night, but when I turn diffuse down on your wood surfaces, everything is fine. Phile is totally right.
I changed some lighting and surfaces and rendered this. I will mail you the LWS and changed LWO's.
btw FG max rays is now 1600, take it to 3200 to get less splotches, AA could use upsample 1 or 2 to get more thin lines into it.
