What's a PWM all about?
I understand that a Pulse Width Modulator (PWM) is used to control the maximum amperage draw, but I'm curious if there are other advantages also? For example, can the percentage of electrolyte in solution be increased significantly, thus allowing for higher immediate amperage draw at startup? If yes, does a higher percentage of electrolyte in solution produce more hydrogen gas with less total amperage? Or is there a sweet spot after which any additional elecrolyte actually decreases the hydrogen output?

Generally I'm very interested to know what other advantages a PWM offers, because if amperage control is the lone reason, it hardly seems worth it to me.

There would be a sweet spot if your electrodes were able to resonate. Otherwise it will only allow you to control your amperage withing a range.

It allows you to have a higher freeze point on your solution. By increasing your solution concentration you can turn the PWM up for full amps in cold weather and get more HHO production until the solution warms up, then turn in down to maintain the HHO production you desire.
