I remember trying to set up my first scope too. Still have to think about it sometimes.
I did my ranging first, and marked my wheel. Then when I had a chance I would shoot whatever range and note clicks for that range. I never started at one point then worked forward or backwards.
It's quite a task to get it all done at once so I did it in chunks. And in theory, they should fall into place.
Once I had them all noted down I chose to put the clicks on my wheel.
