How long do you run eigenvector centrality?

[Russell Jurney]

I'm analyzing Github data, and I've created links between repository nodes based on users co-forking a project (one co_forked link for each user who forks each pair of projects). I am running an eigenvector centrality on these links to create a project rating for Github projects (code below). 

I have tried the algorithm for different timeLimits, from five seconds to ten minutes... and I get very different results each time I change the period. Which one is right, how will I know, and what is the right way to think about this problem?

// Get top 20 by co_forked centrality

g.V().hasLabel('repo').

repeat(

groupCount('m').

by('repoName').

out('co_forked').

timeLimit(60000)

).

times(5).

cap('m').

order(local).

by(values, decr).

limit(local, 20).

next()
