Overexposed P30 files in LR

I have posted something about this before, but are still puzzled about it.

When I expose my P30 correct according to lightmeter/histogram for C1, the
files are very underexposed when opend in LR or PS.

I posted this question in another forum if anybody had the same experience.
Nobody had.

I went to my dealer and he tried with his P30 and P45 and got the same results
as me.

So I ask again - James or you other guys using P30/P45. WITHOUT auto in
PS and LR, do you see underexposed files?

If I want "correct" exposed files in LR, they are useless ( overexposed) in C1.
