Hello, I've been trying to apply a ground scale factor to my state plane coordinates in trimble access and TBC, but when I enter the scale factor it doesn't seem like its being applied properly. 

With the scale factor I'm using, my control point should be:

421,173.7664 N * 1.0001485221 = 421,236.3200 Y
1,889,225.8327 E * 1.0001485221 = 1,889,506.4245 X

But instead TBC is converting it to:

421235.811 N
1889214.274 E

Any idea why this is happening?
