First of all, replicas can be off in terms of counts for the soft commit interval. The commits don't all happen on the replicas at the same wall-clock time. Solr promises eventual consistency, in this case NOW-autocommit time.
So my first question is whether the replicas in the shard are inconsistent as of, say, NOW-your_soft_commit_time. I'd add a fudge factor of 10 seconds earlier just to be sure I was past autowarming. This does require that there be a time stamp. Absent a timestamp, you could suspend indexing for a few minutes and run the test like below. Adding &distrib=false to your command and directing it at a specific _core_ (something like collection1_shard1_replica1) will only return data from that core. When you say you index every minute, I'm guessing you only index for part of that minute, is that true? In that case you might get more consistency if, instead of relying totally on your autoconfig settings, specify commitWithin on your update command. That should force the commits to happen more closely in-sync, although still not perfect. Another option if you're totally and completely sure that your commits happen _only_ from your indexing program is to fire the commit at the end of the run from your SolrJ program.
