Dear Stephen,
I like your observation. Well done. However, we corrected this event in the final documents uploaded in this lesson (week number 5). Now the minutes of meeting and the project team discussion results are the same. Regarding the duration of the 107 days it was working days not calendar days. However, we changed this activity type to milestone instead of activity to avoid such dispute. It is better to make activities with certain start/finish dates as a milestone rather than regular activity type.
Best Regards,
Hany Ismael
