How to extract the last curve of each massive addition count?

Hello, the image represents what I am trying to do.
I have two lists, I want to extract every 5 meters approximately the last line to which this sum corresponds.
I have not been able to understand how to address this problem. any help would be great thanks

that works thank you very much :grinning:

However can I ask something else?
if I change the series of elements. I see that the values very close to each other share the same point.
How can I average those items that have those characteristics?

You can do average like this , i don’t know about your other question;
maybe with converting numbers to points or logic math with floor and ceiling

it’s about item 27 shown on the panel. it is not taken into account in the boolean as a value close to 35
