-adjust mastery term spacing (days between seeing terms) in user settings, or schedule settings
-set schedule mode to quick and simple (boosts mastery when any vector answered right) vs slow and thorough (boost mastery after all vectors answered right)
-(with slow and thorough) less vectors on a schedule means less time
-set the "When I answer something incorrectly" settings in user settings to "drop the mastery a bit"
You can adjust the number of new terms on a schedule upwards (or downwards) on a schedule at anytime. Newer terms will naturally appear more often in quizzing as they have lower mastery levels.
