Comment by SLOTH on Alex

@SLOTH Clearification, Most of time Manga covers 80-90% of Light Novel but the Anime covers 60-70% of light novel.

@SLOTH the difference is that manga have to wait a month to go to the next chapter. Meanwhile the anime is covering 1 to 4 chapters of manga with just a week. If the anime has s3 now, The manga will go far behind. They have to wait at least 1.5 years to let the manga catch up
