These are in the manual (at least in Vers. 6, which is available on the PS Audio website.

I’ve copied and pasted the relevant passages below.

Variable MultiWave: Since the introduction of the PerfectWave series of Power Plants users have had only two options for their regenerated outputs: pure sine wave or MultiWave. Now, with the addition of Variable Multwave, we've extended those two options to seven: pure sine wave or one of six MultiWave choices. Users are empowered to vary the strength of the MultiWave output according to the needs of the equipment and the resulting performance benefits.
MultiWave option settings are chosen from the front panel on the setup screen menu. The choice is labeled MW Strength and users can choose stregth levels 1 through 6. Each progressive step increases the charging time of the Power Plant's output waveform. Longer charging times, taking place at the peak of the Power Plant's output sine wave, lowers the connected equipment's power supply ripple, much the same way as increasing the power supply capacitance of connected equipment. Just imagine adding 50% more power supply capacitance to your connected equipment.
The original MultiWave function on P5 and P10 Power Plants is the same as Variable MultiWave strength level four. Strength levels one through three are lower strength waves while strength levels five and six are the highest strength levels of MultiWave ever offered.

Try different MultiWave strength levels to suit your system’s needs for best sound.

Considerations: Variable MultiWave strength levels five and six require more energy to be delivered from the regenerator in the Power Plant than the present single MultiWave selection does. If your Power Plant is already close to maximum power output or is working hard to make up for low input voltage, you may notice an increase in output distortion of the Power Plant when using Variable MultiWave setting five and six. It is recommended, in these cases, to stay with Variable MultiWave strength four or below to help maintain low output distortion to your equipment.

Phase Tune: Phase tune adjusts the time relationship (phase) between the incoming voltage waveform and the regenerated waveform. There are a few places that have unusual distortion which includes a very substantial time lag (phase shift) relative to the fundamental. In these situations the default setting of the Power Plant didn’t perform as well as it could. 99% of the time, the default setting (0) is appropriate and no adjustment is necessary. If your Power Plant is consistently delivering less than 0.5% distortion (THD) in Sine mode, you should not need to make any adjustments. Below are the conditions under which you might want to adjust this setting:

  1. Your power from the utility has extremely high distortion, over about 8%.
  2. Your power from the utility is typically more than 10V (15V for 230V models) away from your desired output setting.
  3. Your Power Plant is not able to reduce the incoming distortion by a factor of 10.

In other words, if your THD In reading is 8.0%, and your THD Out is 0.5%, your Power Plant is performing well. If your THD Out reading is 1.0% you may benefit from adjusting the Phase Tune. Please keep in mind that the Power Plant is correcting both THD and voltage errors. If your incoming voltage is within a few volts of the output setting, your Power Plant will be able to devote most of

its capability to correcting the distortion. If the voltage is 10 volts or more away from the setting, the Power Plant is not going to be able to correct the THD as well. So if your utility voltage is more than 10V off, and you are seeing your THD reduced by only a factor of 5, this is probably normal.
The procedure for setting the Phase Tune is simple. Experiment with different Phase Tune settings and see what setting gives you the lowest output THD reading. The optimum setting depends on how much distortion is on your power and what it looks like. Unfortunately there is no way to predict what it will be.
