Can you see a trend?

Another way to visualize it:

This confirms the conclusion a paper by Ben Hu, Shi Zheng Li et al:

“SARSr-CoV evolution is strongly correlated with their geographical origin, but not host species.” (Hu et al., 2017)"

So let's see.

What should be the logical step right now to investigate the origins?

1. Invite scientists to come and sample in Yunnan and especially Mojiang, and release available sequences and sampling information, or

2. Block any access to the Mojiang mine, confiscate samples from the few Chinese scientists who somehow managed to get there, take all viral DBs offline and firmly tell the WHO to go sample elsewhere.

Well, you know the story.
