different number of followers, depending on how fetched

[sorin-costea]

Hi all, how is it possible that while getFollowersCount() returns a certain value, actually requesting the followers returns about 10% duplicate names - yielding a 10% lower real number of followers? See code below - the final map will be noticeably smaller than the initial count! Is this an API issue or a Jumblr one?
A lesser issue would be that, although the options say 20, the followers() call will usually return anything between 15-20...
Thank you!

            int numFollowers = myBlog.getFollowersCount();
            logger.info("Followers: " + numFollowers);
            Map<String, JsonObject> mapFollowers = new HashMap<>();
            int offset = 0;
            do {
                options.put("offset", Integer.toString(offset));
                List<User> followers = myBlog.followers(options);
                int fetched = followers.size();
                logger.info(offset + "/" + fetched);
                offset += fetched;
                for (User follower : followers) {
                    logger.info("follower: " + follower.getName());
                }
            } while (fetched > 0);
            logger.info("Real map: " + mapFollowers.size());
