Agreed, with one correction: 26.57 degrees , is actually what you would want. A slope with a ratio of 1:2 = 26.57 degrees. I only say this because such intuition is common and can result in mistakes that are hard to debug. I intuited the same a while back and embedded 22.5 degrees in code for physics for a game I was working on... That mathematical error sat in the code for a year before I realized my mistake and corrected it.
