I have yet to see an argument for using a charged cutting lap that would persude me to switch from a sintered or solid steel impreginagted cutting lap.

You know, I've started doing more and more with my 325/360 depending on the material since trying to place initial facets with 600 was super slow, sometimes even a 260 for bigger harder stuff like lab sapphire or topaz. But it's also material-dependent - definitely can't get away with that on fluorite, apatite, or spodumenes so for those I really do mainly stick to the 600.
I recently figured out that time-saving step too for garnet/tourmaline/sapphire, after I packed up my faceting setup to work at a friend's house, and forgot my sintered 600. 360, followed by 3k Diastik on Zn+, finished with 100k Blakstik on Diamatrix, worked like a charm and saved me at least an hour.

Was the 360 mesh lap plated or sintered? Was it new or worn?

I'd strongly suggest you start with plated laps.
Having to charge your laps, knowing when it's charged, knowing when it's cutting the way it should, knowing when to clean, knowing when it's time to recharge... to hell with all that.
