Ah, I remember the difference now, that's why I use su= and sw=. This 
mix of different units is... irritating.

I corrected the FAQ now to use su+sw:
And I mentioned "swidth" and "sunit" in a sentence in the end.

I'd say using su+sw is more future proof than swidth+sunit, as 4K sector 
drives will become standard, and then using 512B units will be outdated 
anyway, right? And using su+sw seems simpler to me to explain. YMMV,
