How to Autoamte T Shirt Sizing

[Sam]

Hello all, 

I have story points that roll-up from story to epic - this works well as I can see the total sum of story points on the epic.

However, I am hoping to set the T-Shirt sizing according to the total story points on the epic. I have a rule that semi works, but I noticed the T-Shirt size does not always change accordingly. At times it seems to get stuck on the previous size no matter how often I edit the story points

Sizing:

0 -20 = XS
21 - 40 = S
41 - 60 = M
61 - 80 = L
81 or Greater = XL

so if on the epic, 'Size Estimate' = 19 then, 'Size Estimate' should- XS, and so on...

Can you please view my rule and let me know if there is a better approach? I only added the first two sizes for the automation, it all else looks the same. 


The size is set here, using the edit option from the Action automations:

Hi @Sam 

If i understand correctly, you already have a working automation that set the story point of the epic to the sum of children's story point?

If so, then why dont you validate the size with that automation and set the tshirt size ?
