Difficult to be sure without being on site but change in VTF will change SRA at the same VTA setting. It may be worth while to adjust for a lower VTA setting and try 2.2g again.
You may have set the VTA too high and required a increased VTF to maintain proper SRA. This is done at the expense of misaligning the coil.
If your VTF gauge is thicker than the record, it will also measure a slightly higher VTF than actual VTF at the record surface.
