DAX Code Help

I have a sample data with Survey waves (from 5 different time periods 1 to 5). 

Need help in creating the below 3 columns highlighted in green. 

1. Latest Wave column: Need to create a new column in Power BI using DAX. This should be based on "Maximum" value from Survey_Wave column. If true 1 or else 0. 

2. Previous Wave column: Need to create a new column in Power BI using DAX. This should be based on "Maximum" value -1 from Survey_Wave column. If true 1 or else 0. 

3. Last 3 waves columns: Need to create a new column in Power BI using DAX. This should be based on "Top 3" value from Survey_Wave column. If true 1 or else 0. 

It is important to note that the code should be dynamic as the Survey_Wave column over time will get more values (6, 7 .... etc going forward in time)

 

Desired Result as below:

Hi, 

Here is one way to do this:

Data:

Dax:

Latest =
var _max = MAX('Table (35)'[survey_wave]) return
IF('Table (35)'[survey_wave] = _max,1,0)

2. 
Latest =
var _max = MAX('Table (35)'[survey_wave])-1 return
IF('Table (35)'[survey_wave] = _max,1,0)

top 3 = 
var _max = MAX('Table (35)'[survey_wave])-2 return
IF('Table (35)'[survey_wave] >= _max,1,0)


Test (added data):
