It's more than just reproducing the standard flavor. By not measuring sometimes you'll get something very good, but because you didn't measure anything you won't know what you did that caused it to be good and won't be able to do it again.

Measuring doesn't preclude experimentation. You should copy your recipe, mark what changes you plan to make, then try it. If it works, you have a record. If it doesn't work, you can add a memo to know not to try that again.
