I have a question regarding the dollar bill test. I understand what it is and how to do it I was just wondering how tight of a seal do you guys consider to be tight? In other words do you guys put a bill into your doors and your not able to pull it out at all for fear of it ripping in half, or is a little resistance when pulling it out considered to be a successful test as well? I understand if you can pull it out easily obviously you have a problem. Just wanted to get your feedback. Thanks for the help.
