I don't really believe that every positive SMC ever goes through the same progression as Ra, personally. That wouldn't make sense to me.
That only establishes that the Ra civilization was oriented that way, it was through their own orientation that lead to the acceleration. I don't think "harmony" looks the same for every civilization pushing fourth-density.
They also said they had to spend extra time in 5th density due to their biases gained through 3rd and 4th, so there's clearly ups and downs to the orientation.
The "lengths" of the path are relative to the efforts of the entities traversing them as it appears to me.
Ra does say the positive path can be more 'efficient', but that doesn't necessarily always mean faster.
