How precise is the Dualaxis AD22302 accelerometer?

Question

Hello everyone 
 
 I am a mechanical engineering student currently working on a project, 
 wich involves working with an AD22302 Dual-Axis accelerometer. 
 It is capable of measuring +/- 70g on the x-axis wich is the one I am currently using. 
 
 My question is: 
 what is the accuracy of the device? I am able to find the non-linearity in the datasheet (attached to the post) 
 but that is about it and I need the overall accuracy. Any kind of help will be highly appreciated

If we were being very conservative, I would say that the difference in the peak shock, with respect to the no-shock output, should be better than 10% accurate, assuming that the majority of the energy is coming from the axis in question. The cross-axis behaviors present another, independent error source that can reach 5% as well. Since you are measuring 2x off of your present expectation, I would suspect that there are other errors in this process, which are not related to the sensor's behaviors.)
