Generally speaking, the duplicate checking rate of HowNet is 2%~3% higher than that of PaperPass, so if your duplicate checking rate of PaperPass is 24%, the duplicate checking rate of HowNet may be around 26%~27%. However, for personal papers, due to the different databases and algorithms used by HowNet and PaperPass, it is impossible to accurately predict the duplicate checking rate of HowNet.
It is suggested that HowNet be used for the final duplicate check to ensure the originality of the paper and meet the requirements of the school.
