The Mobil 10/40 does claim to meet Jaso but not registered with Jaso as meeting the standard.
Im not sure what point you are looking for *L* (just talking)
You left diesel oils on your list that do not claim to meet Jaso standards but took others off your list for the same reason.
...
This is just make sure we keep the words "claim" and "registered/approved" separate.
All the diesel oils remained on the list, except for the Castrol GTX and two of the Mystiks (if you could even call those diesel oils, I dunno for sure), because they meet the Allison C4 and/or Caterpillar TO-4 specs, ..
Moral of the story is that all the oils now on this list explicitly claim to meet or exceed one of the 3 wet-clutch certifications -- JASO MA, Allison C4, or Caterpillar TO-4. The last two aren't motorcycle-specific certs, but to the best of my knowledge, they are indeed wet-clutch certs.
No big deal, not at all, I always used either 15/40 diesel oil of Valvoine 20/50 4 stroke oil in my metrics, its just I am not seeing some of the ratings you are talking about in your spreadsheet, but then again, I have never checked any rating for diesel oil simply because they do not claim to meet Jaso (except Rotella which I did not like), as far as personal theories of non Jaso diesel oils meeting your requirements with other ratings that is personal decision and no problem with that and your certainly welcome to leave whatever you want off of your list.
I only checked one which I did use at times and I am not seeing the rating here that you have in your spreadsheet, example ...
