If it is a school graduation thesis, it needs to be divided into two parts: professional thesis and doctoral thesis. Generally speaking, it is enough to check that the weight of this paper is within 30%, but some schools and majors require it to be more important and strict. Then the weight check of doctoral dissertations is strict, generally between 15%-25%, and there are many weight checks below 10%-5%. Then the paper's duplicate check of 25 is in line with the standards of this college's papers, and this duplicate check value is still safe. But for the master's thesis, the duplicate checking rate is beyond the standard, and there are still many repetitions.
Then we should divide the journal papers into general journals and core journals to discuss. The duplicate checking of ordinary periodicals is generally not higher than 30%, but the requirement of national periodicals cannot be higher than 25%. The duplicate checking of core journals is very strict, ranging from 10% to 20%, and those below 10% and below 5% abound. So for most ordinary journals, the paper's duplicate checking is still up to standard, but for national journals, this value is very dangerous, so we still have to revise the paper. Then it is obviously unqualified for core journals, and the length of duplicate checking is still very high, which requires us to greatly reduce the weight.
So whether the most important examination of the paper is 25 depends on the specific examination standard of your paper.
When you find that your paper has a high duplicate checking rate, we should not panic, because it is very normal for papers with strict duplicate checking requirements. We need to find a suitable method to reduce the weight of our paper and revise it. Don't lose weight blindly, otherwise the effect may be worse than not losing weight.
