Low effort

I am in the middle of a personal experiment, that's always quite fun. I am trying, for a change, to keep a low effort level on an assignment. I am in class all this week, for another compulsory PhD-course. This one seems quite interesting and useful, and goes under the name Oral Communication. We have classes all week, but today we are on our own, preparing a presentation we are to give the others on thursday. Normally, I would work hours and hours on an assignment like this, learning it by heart, and practising until perfect. This time I have decided to put in no more work than 4 hours in total, which I here refer to "low/minimal" effort. We had 2 papers to read, a written part to hand in with explanations to why we chose the layout/presentation techniques we did, and then prepare the oral presentation. I have so far put in 3 hours and 40 minutes, and I am almost done. I need some detail work on my presentation only, and addition of one sentence on my written assignment, and I am quite sure I will make it.

I wonder how my personal experiment shall end. Will the outcome of my presentation (the judgement from the audience/teacher) will be any different now, with this minimum effort, than I normally get on presentations on which I have put maximal effort? Or if it at least will be good enough? Maybe there is nothing wrong with "only" being good enough? It's just a thought.
