Determine percentage of repeat callers (beast Mode or ETL?)

Good morning. We've been trying to create a beast mode to help us determine the percentage of repeat callers and while I can picture in my mind what needs to be done, we've been unable to determine a working calcuation for it.

In the image below, there are 14 distinct companies/phone#'s and a total of 33 calls. Of the 14 distinct companies/phone#'s, a total of 8 have called in more than once, so that would equate to 57% of our callers being repeat callers.

Can this be accomplished with a beast mode, or is it something we'd need to do in ETL, i.e. collpase columns to aggregate and then create a beast mode at the card level? I'm not a math whiz, but thought it would be easier than this!

If anything is needed to help, please don't hesitate to ask, and any assistance will be greatly appreciated; thanks in advance...

Just a few of the many attempts made are:

CASE WHEN
(COUNT(DISTINCT`PhoneNumber`) - COUNT(`PhoneNumber`)) = COUNT(DISTINCT `PhoneNumber`) THEN 1 ELSE 0 END / `Callsid`
CASE WHEN
(COUNT(DISTINCT`PhoneNumber`) - COUNT(`PhoneNumber`)) THEN 1 ELSE 0 END / `Callsid` - 100
(COUNT(`PhoneNumber`) - COUNT(DISTINCT `PhoneNumber`)) / COUNT(DISTINCT `PhoneNumber`)

Helpful links we thought could help us resolve this:

1) https://dojo.domo.com/t5/Domo-Dojo-8482-Documentation/Calculate-percentage-of-a-subset-to-the-total-in-Beast-Mode/ta-p/1922 (this would likely work fine for a single bar chart, but unable to get it to work since we want the % of total in a bar, and the total # of calls as a line)

We're working on doing this in an ETL. Thanks

This would be the top level of the card, and we'll use a table to drill down to view the repeat offenders in the hopes of finding ways to minimize the issue.

Any thoughts or suggestions on this? Apologies if the submission was long winded or possibly confusing, trying to simplify the request here:

It's understood COUNT(DISTINCT `PhoneNumber`) will return a count of unique phones #'s, which obviously we'll require, but the problem we're having is determining the count of the unique phone #'s returned that have called in to our call center more than 1x.

From there, it's likely a simple calculation of dividing those distinct phone#'s that called in more than 1x by either total calls/phone #'s to provide us a percentage of repeat callers, but we've been unable to figure out how to get that piece of the equation, i.e. a count of unique phone #'s that have more than one (1) call in.

Thank you...
