For my years of reserve I religiously checked and screenshotted my HI3 within seconds of blocking in. Quite a few times my phone would blow up minutes later, but I was already released. From those voicemails I could tell Scheduling wanted me to think I had to call them back, but they never threw the PG at me for that (considering how often they PG'ed me for other inane reasons, that means they knew I checked the HI3 and that I was free).
