I tried a simultaneous comparison test to see real time what values I should be receiving, and the values are vastly different. In the attached excel file, I have two sets of data, to the right are three columns, one for each axis, and the other set of data is the serial monitor output. Just looking at the first few lines show that the data is not correct. Even with a different constant multiplied by the output variable, these numbers are not my data.
