On a light week, probably about 3 to 4 hours.
Typical is probably closer to 6 to 8 hours.
Heavy weeks, like this week where my boss is leaving, I'm out on vacation until 2022 come the weekend, and everyone is trying to get their shit in order before both happen, I have about 14 hours of meetings on my calendar, essentially assuring I'm not productive with anything outside of them!
