Need info for the Time Stretch

Here’s a new one for me. When in the project you select all and choose Time Stretch as a process, where in the Time Stretch Panel does it tell you what numbers indicate the projects current state. What I mean is I want to slow down the whole tempo of a song so I can follow the tempo at a slower pace to play bass.(I don’t normally play bass). But after I’m done recording I want to speed it back up to the original tempo. What can I use as a reference to adjust the various parameters in the Time Stretch Panel to go back to the original speed or tempo?
This is after I Bounce or Render in Place.
