We just woke up Jan and wanted to add some confirmation to your theory expressed earlier in this thread:
"My hypothesis interprets the sharpness drop over the first night as an edge misalignment caused by the relaxation of major part of residual stresses in the edge after sharpening. Stropping after the first night probably does not generate additional residual stress in the edge and so the smaller sharpness drop over the second night can be interpreted as relaxation of the minor part of the remained residual stresses generated by the initial sharpening. "
This reduction in overnight sharpness level does decrease after subsequent stroppings. We've noted this over a period of years now.
