Hi @bloke125,
You can measure cycle time in particular statuses using historical measures with dimension Transition Status. Those measures represent data from issue change history. There are a list and description of those metrics and how those work:
https://docs.eazybi.com/eazybijira/data-import/jira-issues-import/import-issue-change-history
We have created several templates fo Cycle time reports and solutions you might want to start with.
Report templates are available in the Demo account. You might want to start with those:

And several solutions are described in listed Community posts as well:
