I see a lot of references to 3 Day Potty Training. Is the one everyone talks about and uses this link?

I have read this PDF and wondered if it's the same for purchase above?

I'm planning to give it a try this month (or next), even though I have low expectations with a 20-month old. Any other tips or links suggested to read?
