In my case z-offset is set to -0.25mm (the thickness of the business card I used to level my bed).
The initial gap you use for leveling doesn't need to be compensated for in Z height. Most of that initial gap is taken up by thermal expansion of the hotend. That is as long as you use a thin piece of paper. A business card is 3-4 as times as thick as a 20-24# paper.
