Chance of Upgrade

Last Delta flight before switching to Alaska/American since very upset with changes to SkyMiles (psi, it’s been a fun five years #PleaseFixSkyMiles). Likely staying put there for a while unless massive changes to their programs…. Anyway, I really wanted to fly Delta One for this. Unfortunately, Delta managed to sell 6 seats in 2 days, and I’m kicking myself for not purchasing the upgrade. From everyone’s experience, what are the chances of two people in Delta One either electing for Same Day Change or just straight up missing their flight? I’m in Premium Select, but not the same as Delta One (this plane is actually the first one I flew Delta One on, so would be a cool way to send things off).
