I suppose it depends on who the data is from!

I'm happy to take your word on it!
I suppose I have been conflating tension and compliance. My aim is obviously to make this guitar as easy to play as possible. I'll be giving her the lowest action I can. The headstock is going to be as small as I can get away with, still yet to plan it exactly but I'm ordering single tuners so as to set them closer to each other. I guess that means I won't have the long back string length to give extra compliance.
I've chosen extra hard tension strings because I though standards would be too loose at this scale, even up at open G. Maybe I need to re-investigate that. DennisK very kindly tested a classical capoed at about 480mm and then tuned to E for me... Maybe I'll have to ask if he can do the same up to open G and see if the strings are still floppy [I don't own a classical - not made one before]. That should be a decent indication, shouldn't it? (I need to choose strings ASAP so I can make the dummy neck)
I did find on my last guitar that the saddle break angle affected compliance. And relief. I'm slowly experiencing first hand all these things I've read about!
