How should I punctuate the following sentece with the given logical structure when I want to use conjuction "if" only one time and a conjuction "and" to seperate the conditions?
Logical structure: [Statement] is true if [Condition #1] and [Condition #2] is true.
"This method is implemented if it's impossible to verify the results of the process, and the shorcomings may not be revealed until the product is used."
Should a comma be between "process" & "and"?
And what if I use a conjuction "or" (with OR logical relation) instead of "and"? How would the presence or lack of a comma would affect the sentence grammarly and logically?
"This method is implemented if it's impossible to verify the results of the process, or the shorcomings may not be revealed until the product is used."
