True enough. And, indeed, I find that the velocities are pretty similar.
For interest's sake, here are the numbers:
Step # Max diff RMS diff
------ -------- --------
1 0.0002274 0.0000364
2 0.0004390 0.0000698
3 0.0006116 0.0000981
4 0.0007483 0.0001199
5 0.0008979 0.0001349
6 0.0011089 0.0001438
7 0.0012832 0.0001480
8 0.0014209 0.0001497
9 0.0015147 0.0001515
10 0.0015537 0.0001554
Given these small differences, I've decided it's safe to copy and paste the velocities from the unwrapped file into its wrapped counterpart.
Cheers,
Ben
