question about gradient shimming

Here at WWU, we have 2 instruments running VnmrJ 1.1D:
Inova 500 MHz and Mercury 300 MHz.

When doing gradient shimming on the 500, all is fine,
but when doing gradient shimming on the 300 (Varian 14 set shims),
I (or the user) needs to usually touch up the Z1C and Z2C shims.
The gradient maps look good.

Something easy I'm missing here?
