Alternatives to fining for women who miss work week/recruitment?

[KSUViolet06]

My chapter operates on a point system so every Refinement Week (the week we spend prepping for recruitment) event is worth a certain # of points. Each month, a member must make 85% of the total points for that month. Obviously if you miss Refinement Week events without a valid excuse, you won't get points for them. If you don't get them, you won't make your 85%. If you fail to make your 85%, you aren't permitted to attend ANY scheduled social event (date party, semi-formal, etc) for the next month.
