Clearing up the update plan

Many of you are likely confused by the various announcements I've made on some websites I frequent. That's because I wasn't quite sure by my plan yet myself. Now I've put it together, even if it's no less confusing.
 
Updates shall be ready every ten days, on the 5th, 15th and 25th of each month. An eception is made by double-length strips. They take as much time as two normal ones, which is why they get appropriate slots: eg. if one was to be ready on the 15th, it will be posted on the 20th, 25th will be without update and the next strip, if it's normal length, on 5th of the following month (if it was a double again, then the 10th.)
