Workload Units Charging very Inconsistent

Now I’m seeing an individual data request, that I can not drill into, in order to see what it is from

I also see the RG text based as 0.47 WUs

The main search for Ports in the RG of data type Port is not showing as a Search now, but it does show as an aggregate search and real time search

And that aggregate search of 0.20 is not actually attributed to the search in the RG itself, but is instead attributed to the Text element that references the RG of type Ports count. This has been explained to me by support and I understand this now thanks to @georgecollier reply in another post. But what doesn’t make sense is why the cost of the search in the RG is not applied as it was previously, with such inconsistent and dramatically different costs ranging from 0.37 - 298 WUs?
