Explanation on estimation statistics

[ליאור בראודה]

Hello, I have a question if anyone could help me.

I have a jira data center instance v8.20.7, and I was trying to find an explanation on the different estimation statistics there are in the board configuration, and I was not able to find information on a few of them.

1. What is the difference between "Story Points" estimation and "Original Story Points" estimation?

2. What is the "Task Progress" estimation? and how does it work?

3. What is the "Number Test Field" estimation? and how does it work?

Thank you in advance😊
