Each article shows how to read one document you already have: a pay application, a waiver, or a change order. It does not create that document, and it does not replace the contract it belongs to.
Draw Jacket does not say what an owner must pay, whether a waiver is valid, whether a lien can be filed, or how a dispute ends. It does not tell you to sign, to refuse a check, or to stop work. Those decisions belong to the parties named on the paper and to people licensed to advise them.
A dollar amount, a percent, or a count of days that is marked as an illustrative example is made up so the columns are easy to follow. It is not a bid, not a schedule of values from a real job, and not a prediction of what you will be paid.
Jobs differ. A form that looks like the one in an article can still name a different through-date, a different retainage line, or a different signer. Read the page in your hand. If the article and your paper disagree, your paper is the one that applies to your job.
