DAX code for comparing dates not working?

I have an open date and close date in my table, and have them related via inactive links to a date table. I historically have used the following rolling measures to capture opens/closures within flexible time periods such as the following:

 

Created 4XCycle Day Rolling Measure = Calculate( DISTINCTCOUNT(Table[Key]), USERELATIONSHIP('Date'[Date], Table[CreateLink]), FILTER(Table, Table[CreateLink]>=(Max('Date'[Date])-(4*[Cycle Length])) && Table[CreateLink]<Max('Date'[Date])))

 

Cycle Length is a numerical what if parameter that people can adjust.

 

This has stopped working in the past few weeks. Anything wrong that people can see?

Solved it myself - for some reason it previously defaulted to "today" as a max on the dates. Now that has to be declared specifically so you need to do the following: Created 4XCycle Day Rolling Measure = Calculate( DISTINCTCOUNT(Table[Key]), USERELATIONSHIP('Date'[Date], Table[CreateLink]), FILTER(Table, Table[CreateLink]>=Min(([Todaysdate]-(4*[Cycle Length])),(Max('Date'[Date])-(4*[Cycle Length]))), FILTER(Table, Table[CreateLink]

The data is sensitive internal stuff. Date table is just the date table from https://github.com/sql-bi/DaxDateTemplate I'm just wondering if there's something wrong with my DAX syntax or something that would cause it to fail when the year flipped over, as I'm at a loss otherwise.
