Wally would agree with you, Zaikesman. I have heard him say pretty much the same thing about how he believes it is VTF changes that we hear when we tweak VTA since the change in SRA is extremely small.
I don't adjust for each record, but if I detect something I will tweak VTA up or down. Most time this is less than one turn on the VTA adjustment. Is it that tiny change in SRA, or is it really that tiny change in VTF due to raising or lowering? I don't know. HOwever, it is far easier to change VTA on the fly than VTF on the fly. :-)
