For the record, not to answer any questions because, ... well, ... I can only speak for one.
typically riding racy road bikes with a double crankset, when I ride one of my triples - the hips feel strange at first. On one Campy10 triple the feeling persists most of a 30mile ride. Not exactly pain, just different. When riding that triple for a full week over 400miles, there was no problem.
I prefer a narrow-ish Q. But being over 6'+, & a bit leggy - I think it is not a major concern for me.

I personally don't like narrow. My fixed gear has omnium cranks which have are 145mm q according to the internet and they just feel really oddly narrow. Like when I stand to mash the pedals I feel like I'm trying to balance on a very narrow ledge, there just isn't the support I'm looking for. I'm much happier on my bikes with mtb q-factors.

Just a data point:
The Shimano MT-60 Deore triple I'm running on my 85 Fuji (45/42/30) is spec'd, per St. Sheldon, at 150 mm with a 122.5 spindle. I needed a 118 bb to allow the double front derailleur to make the swing. (You can't use a triple FD on half-steps, they hit the middle ring.) So, I'm running at around 145.5-ish at the crank.
But the MKS Urban Platforms and my size 12.5 - 13 feet probably widen things out quite a bit. It seems to me that the real measurement would be CTC across the pedal tops, +/- cleat position if you use them.

In the end, its about the pedal stroke, all of it
Next time you ride and come up to another rider or a group, take a look at the rider in front of you. Watch how the leg extends at the down stroke. Watch how the feet are planted onto the pedal at that bottom of the stroke. Watch how the pelvis moves (rotates) with the pedal stroke. Watch how the knees move horizontally or remains vertically during the pedal stroke (knee drift).

I agree, the term is pretty old. I don't know when I first heard or saw it, but I think it was in the first half of the 1970s.

Of course, in 1990, 126 or 130 mm rear axles were de rigeur, so there was no need to go too wide.
