My results are:

120.175378956
-80799.308982

which looks strange to me, probably because I don't know a lot about statistics. My ΣDAT is

y

29945.480
30002.951
30006.678
30058.926
30114.903
30119.876
30221.977

x

921.773
922.245
982.237
921.687
923.001
983.350
924.059

In the matrix editor I entered the 'x' data in column 1 and the 'y' data in column 2. Is that correct?

The actual survey data is

PT # Northing Easting Elevation Description

248 29945.480 921.773 0.000 PROP_COR
249 30002.951 922.245 0.000 PROP_COR
