Answer: If a paper is repetitive, it won't take long to check it out. It can even be said that the repetition rate is different after just a few days of checking, because the paper network will be updated at any time, and then there will be more natural references. These situations will lead to different repetition rates.

This is related to the update of the discussion library.

Look at the update frequency of your system database.

For example, if you upload and update several new papers in the discussion library you use, it may lead to the change of duplicate checking rate.

Generally speaking, large databases are relatively stable and will not change much in a short time. As long as your paper is not plagiarized, there will be no skyrocketing, only a small range of ups and downs. It is recommended to control it within one month.
