Richard and list, I'm happy to share what I do, though I have no idea how it fits with what anyone else across the country is doing. 1) Temperament wider than 4:2, 5ths slower than "standard", 4ths faster. 2) Mid range wider than 4:2 octaves. 3) 3rds slowest, 10ths faster, 17ths fastest. 4) I look for beatless 16:1 quadruple octaves. This is not all that much wider than 8:1 triple octaves, which used to be my goal. This only works on concert grands. But on a concert grand, beatless quads can be tuned throughout - A0 to C8 (When I was doing triples, I noticed that essentially I already had quads up to C6). I am quite happy with the beating of single and double octaves that results. THis does not sound extreme to the ear, at least to mine. I use an ETD to check, so I don't know how I would produce these results aurally - don't know as I could. C8 is around +60 cents. 5) 17th beat rates in the lowest octave are in the 1 to 2 per second range.
