The initValue of the yOffsetA channel seems to inherit its number from the 'origin 0 -0.333 0' line (near the bottom of the block), probably as soon as the file loads. This is new to me as pose channels, targetGeom, and valueParm, never seem to change their initValue except by Memorize. The staticValue seems to inherit the number entered on the dial, though wether directly or not I don't know, it might get it via the origin line, this seems likely to me. Perhaps strangest of all the k value for yOffsetA in a saved file always seems to be zero.
