Default Tonal Value Accuracy

First off - after doing an image in ALL AUTO MODE - I made a black and white work copy.
Then I took an old Grey card - with a quarter inch peep hole in the center - using peep hole - and found Grey Values that Matched my Grey Card.
Next I opened up my LEVELS TOOL.
In Levels, I worked with the MIDDLE GREY Value (and peep hole) and found a Grey Match at Value 130 on Subject's Shirt. I Saved that Value in B and W.
Next I opened up a color version - made a work copy - and applied the same Value 130 in Levels Tool and saved that copy.
I thought the end result turned out very accurate.
To always have a Grey Value - just take an image with a Grey Card (to find a Value to use) and an image without a Grey Card.
