Loriblackdog,
This is more for general practice.
Always start at 100% then start tweaking each individual pattern. If a pattern is too low you can add additional height up to 999. If a pattern is too high in relation to other patterns reduce the height down to 0 in increments. I normally have to do that for a texture background.
At the end of the day its what you think looks good and what the patterns will give.
You have gotten a lot better.
