Looks good.

One thing you can do rather than having multiple entries is use the poly_wave
waveform (rather than the default linear waveform) which should be able to do
axactly what you are doing with multiple entries (only better as it would be a
continuous nonlinear waveform whereas you have many smaller linear waveforms)
