Well, the whole business is loaded with ad-hoc terms. I guess they mean
'threshold', which should better be called 'acceleration threshold'. My
problems with 'sensitivity' are
1) to me it's something purely physical, as in 'sensor sensitivity'
2) Since Xi2 reports subpixels, it really doesn't change sensitivity in
any sense except the 'on screen vs. device motion' sense
3) increasing it gets you less 'sensitivity'

IMO, that's the most accurate term.
