What is the last data of SEN-14001? Razor 9DOF M0

The datasets:
1996551, 0.01, 0.12, -1.00, 0.73, 0.38, 0.31, 12.15, -66.92, -45.91, 0.0369, -0.7548, -0.6537, -0.0402, 169.71

I command t+a+g+m+q and it should be 1+3+3+3+4 = 14
While the datasets I received is 15. What is the last data?

Any suggestions would be much appreciated!
