The advantage of penholder lies in its high speed, powerful database, strict grades and free search by the school, so it is loved by many students. But the database of each software is different. There are also differences in algorithm. It's hard to say what the repetition rate of HowNet 19% is. You still need to check HowNet at last. It can be high or low, and it is possible to float up and down. If your school uses HowNet, then you must finally use the system consistent with the school to find peace of mind.

Because of the differences in algorithms and databases of different paper duplicate checking systems, the duplicate checking results can not be consistent, and each duplicate checking paper is different, which involves specific analysis of specific problems, but the difference between Pen.com and HowNet is generally 5%- 10%. It is no problem to check the duplicate of the first draft of the paper with pen network system, but it is safer to use the duplicate checking system consistent with the school for the final draft of the paper.

If the databases of the two detection systems are different, the results will be different, generally floating up and down by about 5 points. Pen Net is a one-stop service system for writing and duplicate checking. Cooperation with many domestic universities is generally suitable for junior high school duplicate checking. It is recommended that you use the testing system consistent with the school to test the final version.
