and what's the meaning of %6d?
I use two different Grids. One small for the whole country with low accurancy but even better results (10-20cm) and that big one that should have an better accurancy with an offset off 150m.
The parameters of both calls are the same. I only change the parameter +nadgrids.
The author of the gridfile has tested it within FME and ArcGIS with the expected accurancy (3mm).
