10/20/30 in business idea presentation

Read from somewhere the following pointers when doing a presentation to potential investors.

It's called the 10/20/30 rule of powerpoint.

a) 10 slides at most for your presentation.
b) present no more than 20 minutes.
c) font size no smaller than 30 pts.

The idea is to keep clear & concise with your business idea. The ten topics that a venture capitalist cares about are:

1. Problem
2. Your solution
3. Business model
4. Underlying magic/technology
5. Marketing and sales
6. Competition
7. Team
8. Projections and milestones
9. Status and timeline
10. Summary and call to action

Do you agree with his point?
