work on proof-of-concept for Pseudonym Pairs, scheduling

A design pattern for scheduling tracked from a single variable eventCounter. In the proof-of-concept I've worked on in the past week, eventCounter will be incremented when people start mixing their keys, basically with a check if(now > getTime(State.endOfPeriod) { incrementEventCounter()}, and it is only callable once since once incremented the getTime() will be 28 days into the future, at which point yes, the function should be called again.
