> How do you put numbers in there usually?

Make them up. If you're uncomfortable with this, ask ChatGPT to make them up for you. Most places don't have any real way to measure productivity or rate of feature delivery, so as long as you promise a reasonable number (5-10%) they have no way of contradicting you.

Incremental refactoring is also the other classic way to do this. Slip bits into other tickets until you've slowly dragged the ship around. But it's not always possible.
