The promotion function is driven by 2 aspects:  time-in-grade, and classes attended.

Time-in-grade - Time in grade is that time spent at the student's present rank and is not cumulative from date of any previous promotion. 

Classes attended - For non-seniors, classes attend count towards promotions.  For planning purposes, there are a maximum of 6 classes per week.  Each week fully attended counts as 6 points towards a promotion minimum of 312 points.

Accelerated Promotions

For non-senior levels, promotions for advanced students can be made at the discretion of the Sensei.  An override function is required.
