> Just be careful with extrapolating Figure 5 to all sensors - or even
 a particular one is misleading (as I wrote). It also applies to a 
particular risk scenario, and a particular description model. In no 
way it's generic, but the feeling might be similar in some respects - 
the mechanics of accuracy is improving but then gradually shifts to a 
place where it no longer makes much difference. Still, going for "OK 
so 10 Hz is fine" based on Figure 5 would be not quite proper, in 
general.

100% with you. The current position from implementors is that there's 
a cut off point at 60 Hz beyond which they're not willing to go for 
security reasons.

Both your data and the data provided by @maryammjd above indicate that
 not only this cut off point is arbitrary, but its also to high to 
protect against threats for which we have data.
