Is it normal to get two different tss numbers?

Did a run using garmin device, on my calendar one tss when I open the activity shows another

. I saved and restarted the app.

The bottom number is the completed TSS from what Garmin submitted. The top number is the estimated TSS from when you created the run, said it would be X minutes long, and that estimated RPE would be moderate.

It estimated a TSS pre run based on the data you gave it, time and estimated moderate excertion but when you actually did the run it recalculated the actual TSS base on actual time and HR. Yes that’s normal.
