From the logs, it seems like the second retry (5s) fixes the "normal" cases, so just remove the first retry (0s).
Also from the logs, if a retry doesn't work by the third attempt (10s), it's most likely the "locked" case and retrying further doesn't help. So, reduce one more useless retry attemp.
Removed logging since we've gathered enough data, and that this hook is expected to be hit a lot, so we don't want to clog the logs.
