You need to post you car cover question in that thread! That's a good question and others can learn from your question. I would go with what the chart recommends. There's no need to over think the chart, pick the situation that you are in and select that cover.
I was doing a google search for car covers and I saw your thread detailing what you need and what you don't need in a cover. I have known previously that a car cover can really destroy your vehicle if not used right. However, I am stationed at Camp Pendleton and looking for an outside car cover. I will have the Camaro under a car port until a garage becomes available at my residence and I was thinking of covering the car when it was parked under the car port. I saw that the Covercraft Noah was a recommended outside car cover. I was just wondering if you had any other recommendations before I pulled the trigger on the purchase. Looking to buy this weekend! Thanks.
