I prefer shooting with the 24mm equivalent lens, but there wasn’t enough room for my partner to step back and get the obstacle. 
I wasn’t trying to show off or give myself a challenge I was ready for YDS3 / T4 and then was like “huh I can just walk up this”. I guess technically there’s a short fall risk so it could be T4 for that aspect, it looks more exposed than the T3 example on the wiki if very short (I’m really guessing on SAC details).
It wasn’t that much harder than the following sequence which I think is clearly YDS 2 and (most likely) T3. In poor weather, or if someone wasn’t confident for whatever reason they could hold onto it with their hands (and should at that point!), but I don’t think it counts as “simple climbing” vs walking up something steep enough that using hands_for_balance is expected.
I think for the most part we can do a direct mapping from SAC, allowing for the “unverified_walking” where T1 is clearly split. I’m sure there will be some inconsistencies (people don’t understand SAC, terrain doesn’t meet some sub-requirement, etc), but those already exist and going forward I’d imagine less of them.
From what I saw (skipping around a few times) I’d put it at attentive_walking there are often obstacles, but I only saw one that couldn’t be avoided and it was a pretty simple step up. Most of the obstacles were low angle and well spaced. I think having sets of examples would help - I have a LOT of off-trail photos that I’ve been saving and cataloging for a separate project (with some overlap with this one). I do agree that having more specific language around obstacle types and frequency would be useful. surefooted_hiking would be more in the vein of the T2 example on the wiki, where you’re basically just walking on medium-high angle obstacles for an extended period of time.
update: was looking for some previous photos in a thread here, found it! the first photo here would be casual_walking (unless we want to specific a surface type for it, sand could be problematic for some?). The next four are attentive_walking, the stream crossing would be surefooted_hiking, then there’s a hands_for_balance that leads into technically a move of scrambling but which should probably be a obstacle=mantle or something instead.
This is one I took recently with this value in mind - the sandy bit of easy trail goes over a piece of uneven slab, but it’s only slightly uneven.
1:35 is a great example of surefooted_hiking - but it should either have a path_fall_risk or an exposure hazard on it! I think that’s a perfect example of disambiguating exposure and technique, as marking that as T5 or something due to exposure would be misleading. It is also very different psychologically from the T2 example on the wiki.
2:30 would be hands_for_balance until he starts to go up the pinnacle itself around 2:40 which is definitely scrambling.
It would be useful to have the trail be hands_for_balance up until the base of the pinnacle - I know some people that would basically go to the base of the pinnacle and call it good enough. How to handle the pinnacle itself gets into the node vs way idea that’s been kicking away. I wouldn’t mind the trail at that point having a little “climbing” icon like at the base of climbing routes of boulder problems to clarify the shift.
