Collecting marginals during or after equilibrate

Dear all,
We have a doubt about good practices in collecting vertex marginals during equilibration. In the howto, collection is done with an additional mcmc_equilibrate step with force_niter set to the desired "precision" but in principle this can be done during a single mcmc_equilibrate after mcmc_sweep. We observed some differences (especially when we collect the marginals for groups at each level of the NSBM), so we wonder which would be preferred.
Thanks

The only general recipe here is that one needs first to wait until the
chain equilibrates, and then one needs to collect the marginal for
enough time for the chain to explore the posterior distribution. It's
hard to be more concrete than this, because the necessary times will
vary for each case.

Best,
Tiago
