Guess I'll have to wait about 4 more hours until the single left post published in the last day also gets past the 24 hours perido since publication to see how my Post Bandwidth will change after that, but there is something definetly wrong here that makes the 4 posts per day rule without a penalty not working properly.
If you cannot use the simple rule of posting 4 articles in a time span of 24 hours and have to track your Post Bandwidth with steemd or use tools like yours (very useful BTW, especially for new users) in order to be sure when to publish or not, then you are essentially wasting time for useless things. This, along with the many other things you need to keep track of in order not to get a penalty of some sort for wanting to contribute something good can easily make you loose interest in steemit in no time. Having to waste time on things that don't exactly work as they should, tracking and trying to figure them out when you can spend that time on something more useful such as on writing better quality articles!
