"WebUSP tailing factor T. A tailing peak has a front of greater than 1.0, while a fronting peak has a front of less than 1.0. The U.S. Pharmacopeia (USP) has also recommended measuring tailing factor (T) as the back-to-front ratio of a bisected peak measured at 5% of height. The ratio is made by dividing the total width by twice the front width. " - Fda tailing factor
