Looks like a very nice piece of work. I will try and digest it over the next few days. I know Jeeves is looking forward to your comments, and I sent him a link to your PW thread.
Agreed: the Nikon PW documentation, including the 56 page version I downloaded for use during my brief trial with the loaner units, leaves a bit to be desired.
Like you, most of my speedlgiht work these days is strictly manual, and my six PW Plus II and seven MultiMax units work very well with my heerd of twelve SB800 speedlights and both my Sekonic L-758DR and C500R meters.
Thanks much for your participation. Nice to have you with us.
