Cheers, I'll take a look tomorrow at getting a unit test written and also rebasing it with the latest main branch

[samriley]

I've fixed the failing tests - it was due to a change in the execution order changing. I've added a test for the span timings, let me know if there are any changes you'd like - eg duplicating the test in to the different cases eg when depth is set to 0.
