It takes a while for the statistics to update - it is not instant.
The percentile is based on math. If you had 91% of 500 messages, don't expect the percent to magically reach 95% just because you got 3 - 4 more messages.
You can look at which messages were unanswered by downloading the file in the Star Seller tab. Just follow the links.
