Question about HRM...

So, I just got the Polar FT60 HRM and i have a question. Do you stop the HRM AFTER you cool down and stretch, or right after you stop working out? The reason I ask is because as I was cooling down and stretching I was still burning calories. So, I stopped it today after I did my cool down and stretch and I burned 372 calories in 46 minutes. I assume it's after you cool down because you start the HRM BEFORE you warm up...
