I made the scrape Sunday afternoon around 2pm. First bucks hit it at 8pm that night. Not 6 hours later. This was a brand new mock scrape too.

I simply found a good trail crossing thru the fence line and the overhanging branch seemed to be the perfect spot. I took a shovel and cleared the ground out and then 'scented' it. I think the keys are this.
1. Find a natural place you would find one in the woods. Corner of a field, or field edge. or along a well used trail in the woods.
2. it must have an overhanging branch. As you can see, they like to work that branch and leave their scent on it

Of all my mock scrapes, I've seen deer use them all throughout the year. This particular one is not visible from the house but my other is from the office window and I have a few pics as well as I have watched several deer check them all times of the year.
