Max-effort for starting pitchers

For all those starting pitchers out there, do you guys go max effort every pitch, or do you take back on some pitches?

And, when should you take off velocity?

Well as a starting pitcher, you know that you have to last 5 innings or more, so we dont use exactly 100% Because if we did, it would be hard to pitch 5 innings or more. Relievers on the other hand, can use 100% because they dont usually pitch much more than 2 innings. If you research, relievers generally have a higher average velocity than starters do professionally.
