it doesnt put any more weight on the last release as it would on any other release......
right now its 212/124 = 1.7097
if next week's episode was to have the extreme (which is usually the highest is 3 chapters in an ep), then the ratio becomes
215/125 = 1.7200
in other words, an increase of 0.01
the current trend is 2 chapters per ep, which would make next week most likely
214/125 = 1.7120
and its the fluctuation of these values are only going to decrease as time goes by.
For the sake of practicality, trying to filter out extra details would be unnecessary, since outlier or not, they all affect the final date. And there's no use trying to calculate how much time goes to fillters either, since sometimes there may be whole eps of fillers, while others it may be 2 minutes or less. Besides, leaving the fillers in the calculation only reinforces the current trends.....since its a relatively consistent thing they do. Then you also have to take into account random weeks where there are no manga chapters at all.
Even though there were about 5 episodes of naruto filler eps, there were easily 5 weeks within the past half year where no manga chapters were released. Thus cancelling those out anyway.
and now i lost my train of thought.....and have to leave.......so blah
