So, Vertex uses pagerank which is a probability, which implies it's a number between 0 and 1. Pagerank is distributed as a power law, which means that between an average pagerank and a high pagerank there are 4 or more order of magnitude difference.
Jack dorsey has 1000-10000x the pagerank of a normal person. Power laws are hard to comprehend for the human mind, which is why Profilestr tried different formulas to normalize this score to be between 0 to 100, in ways that make sense.
These formulas were not great, so I suggested they use something like this. It's poorly written but I don't have much time to work out the details.

TLDR; Vertex didn't change anything, the ranks are computed as before, they are simply presented differently to the end users.
This whole conversation is making me more adamant in my belief that ranks should not be displayed to end users.
