I was imbuing a fourth property to a weapon. The imbuing gump informed me that I had a 33.2% chance to successfully imbue the item. This means that, ideally, I have a 1 in 3 chance of successfully imbuing. In reality, I failed 15 straight times, finally succeeding on the 16th attempt. That's a 1 in 16 chance, or 6.2%. Seems like a big discrepancy. Do I just have very, very bad luck?
