Pulse Simulator, screen shot #4:

Combined slippery and choppy quality

This pulse is a combination of the pulses in slide 2 and slide 3. The slippery profile and the choppy profile interact in a nontrivial way. The slipperiness tends to make the pulse smoother in time, and the choppiness tends to make the pulse rougher and more irregular in time. However, when the two are present together, they do not cancel each other out. The resulting pulse has irregularities, but they are smoothed out. The Pulse Simulator can help resolve these apparent paradoxes in descriptions of pulses, and allow you to visualize pulses that are difficult to describe accurately.

This type of pulse may occur when both Interior Dampness or Damp-Heat is present in combination with Stagnation of Blood. The choppy aspect is due to turbulence of blood flow, whereas the smoothed-out profile of the pulse waveform is due to increased viscosity of the blood. According to traditional textbooks, a choppy pulse is described as being like a knife scraping bamboo. However, this is not very descriptive of the pulse above because of the additional slippery-profile factor.
