Say the raw data is  0,1,2,3,4,9,6,7,8
The 9 between 4 and 6 is the problem. It may be a small glitch on the
displacement curve but it is a massive change in velocity. The velocity is 1
till step 4 then it is 5 and then -3 and it then goes back to 1. How do I fix
the 9 !!!!
Maybe be something like check the velocity and if it increases too rapidly,
ignore that point but that could lead into other issues.
