Comic presenting challenge

I'm playing a volley-ball game this weekend with 4 friends! It's at 6pm.

I need to give them the appointment time, and I don't know what to choose!
On the one hand, I don't want to tell them to come too soon, but on the other hand, I haaaaate being late, and they often arrive late! What should I do?
Fortunately, I gathered some data on their likelihood to be late. I'll tell you all about it!



What time should I tell my friends to be at least 99% certain we'll start on time? (X:XXpm)

Access the data and further instruction here.
