### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-devlake/issues?q=is%3Aissue) and found no similar issues.
### What happened
The `Change Failure Rate` can be higher than 100%, which is confusing.
After I checked the doc, the current algorithm is defined as below.

### What do you expect to happen
We should define CFR as:
The number of changes(deployments) that causes failure(incidents) / The number of changes (deployments)
### How to reproduce
Go to DORA dashboard and see the SQL of CFR
### Anything else
