More on SeatGuru

I've been looking up Bus Class seat configurations for Taipei to
Honolulu connections on various airlines, being fussy about details
because these are overnight flights, and I was just on a lengthy UAL
trans-Atlantic flight where the amount of recline was less than adequate.

The usage of "reclining" in SeatGuru don't seem totally consistent:
There are "Lie flat" and "Flat bed", which are surely OK, but also
"Standard Bus Class seats" which are described as "Reclining 170 degrees
recline" (which oughta be OK also) for some models, but just "Reclining"
for other models of the same aircraft in the same airline. Is this just
accidentally inconsistent wording, or a real difference?
