From where?
Since it’s out in the open already anyway, it’s not counted from the starting point or the keystone but from the path between keystones.
I recommend joining a gems discord. There are usually way more people helping out there.
Also, dear devs, this is information everyone could figure out for themselves so no need to change anything because it’s “unfair”. (It’s not. Unfair would be to change everything now so some people would need to spend 2k gems or something because there’s no rhyme nor reason - just saying.)
