One thing to keep in mind to make this test as accurate as possible is:
1. the suspension arm downtravel is close to equal front to back.
2. You do this test on the tires/foam you'll be running with. If you change to a totally different foam you may have to redo this test.
3. the chassis shouldn't bottom out and hit the table. If the chassis hits the table than the natural rate the spring will rebound changes. Select a drop height where the chassis doesn't bottom out.
I think you've pretty much got it figured out! I do a drop test from a few inches but I'll also push one end down at a time as well and watch how fast it rises. I'll also hold the entire car all the way down and let go and watch to see if one end rises faster. You can even just drive it around and observe how it moves but this is really only easy on a real car when you are inside it. There is no one way to do it. The goal is the same. You just need to be able to tell what is happening and it doesn't matter how you do this.
