- the number of insertion histories is calculated based on the load coefficient according to the above condition and the number of insertions under the condition.
- the load coefficient may be a combination of two, three, and four conditions. The more combinations, the higher the load accuracy, which is desirable.
- the load factor without perforation of lid A is 1.0
- the load factor with perforation of lid A is 0.2
- the load factor without perforation of lid B is 0.8
- there is perforation of lid B Is 0.1 and the number of insertions under each condition is 10,000

- the condition without a hard lid perforation is the largest load factor
- the condition with a soft lid perforation is the smallest load factor.
- the load coefficient in the case of perforation may be set to zero. That is, the number of insertion histories is calculated based on the load coefficient by this combination and the number of insertions for each combination.
