WRONG AGAIN. Use your head: The best vented attic would be a suspended roof open on all sides.
You cannot have too many vents-- period. This "bypassing" that is talked about (turbines with gables with power fans, etc.) is not harmful to proper venting.
The key is to have AT LEAST THE MINIMUM REQUIRED VENTING at the soffits and at the top. However, you cannot have "too much venting", and "bypassing" is not a bad thing.
