I have joined two tables in explore and found the difference and rank between two date values using table calculations. Please can someone help me to create a dynamic tier for the column : “delay(in Minutes)” as attached in the image.

What do you mean by dynamic tier? Like creating a sort of bucket? You could grab the max() value of the column and the min() and do some comparisons based on that, perhaps.
Some more info would help answer the question in more detail.

I think he does mean buckets.
At the moment I believe it will only be able to be done using a table calculation with a lot of IF statements.
That is if you can’t achieve the grouping mathematically, for example 0-10.99 then 11-120 anything like that will required calculations
For example: I want the frequency of the count that occurs between 0-5 or 0-10.
If that is not possible, at least frequency of count of the occurrence. For example: How many times 1 is occuring?
