Dear Survey-Dub,
Currently I'm testing new GeoData in comparison with official Grid InQuest II Coordinate Transformation Software. Numbers are exact matching each other.

Belfast Vertical Datum:

Malin Head Vertical Datum

I have few days to finalyze other issues for upcoming GeoData release.

Have a good day!

That look perfect.
I have attached a text file with 3 OSi CORS reference stations, if you would like to test on official published values which are further down in Southern Ireland.
Thanks again for your work on this.
