**U-Factor** - a number associated with each memorized element. It equals to the ratio of the current **interval** and the previously used **interval**. If the element has not been repeated yet, i.e. the previous **interval** is not defined, **U-Factor** equals the first **interval**. The greater the **U-Factor** the greater the increase of the interval between repetitions. For items, **U-Factors** are determined by SuperMemo Algorithm. For topics, **U-Factors** are determined by **A-Factors**. For topics that have already been reviewed at least once, that have not been subject to postpones, **U-Factors** equal **A-Factors**
