Here's a real post, with a Hive SBI upvote of 1.429. That implies a pending balance of 4.287, which is within our estimated range. That's good, it means rshares were not recorded by the chain for additional votes after the main account hit (and if rshares weren't returned by the chain when we ask for the exact rshares after each vote, then they don't come out of your pending balance).
After this upvote, your pending balance would be 2.858
