Subject : Covering hose hole

I discovered something that may not be news to others. If I am veneering with a base inside the bag and the piece does not cover the hole where the hose fitting comes through, the vacuum cycles a lot. Placing a small block to bridge the hole this problem is eliminated. Could it be because the uncovered hole is acting as a diaphragm and is reacting to pressure?
