I didn't overlook the image. You have the same amount of holes at the top as at the bottom and half the holes of the top/bottom in the middle. Instead of an 'X' pattern of holes you should probably have a 'V' pattern and the bottom level may not need any holes at all.
You just said you are going to test it so I don't want to squabble with you. Results are far more important than speculation. It could very well work perfect for you in your environment, just keep an open mind to the outcome.
