Thanks for the comment. The estimation is for a series of feedback items which is fairly common for those types of sittings. In general you can expect a 3 day churn.
>Multiply that by how many team members involved in the meeting
Are you multiplying the full three days by the number of people in the meeting or are you just multiplying the hour of meeting by everyone in the meeting? The 4300 figure would be 100 hours or 3 days for 4 people. Even if there are a few changes, it sounds more like 4 people talking about changes and one person making them, which even with 3 days of changes would only be $1200. The other 3 people can work on other things during those 3 days.
