Should I Factor Into my Testing a "Wait Time" when Changing Workflow?

Should I Factor Into my Testing a "Wait Time" when Changing Workflow?

Hi ZoHo.  I am testing a workflow rule in the Leads module.  I have a question about patience.  

Here's the context.  I've spotted several errors that I've made in the workflow.  With each error, I'll take the following steps:

  1. In Rules, I'll deactivate the workflow, taking the option of deleting all schedule
  2. In Leads, I'll perform a Mass Delete of the Leads I am working with
  3. In Rules, I'll fix my error
  4. In Leads, I'll import the Leads back in
  5. In Rules, I'll activate the fixed workflow
  6. In Leads, I'll Mass Update the Lead Status field because the workflow triggers on a Field Update to Lead Status
My question is how patient should I be before the workflow triggers?  In my case, when I've completed steps 4, 5, and especially step 6, shouldn't I see the results of the triggered workflow immediately, or is there a delay that I should be aware of?
