Obtaining book and Monthly Contest

I managed to get the book Making Pasta without making 5 star dishes for each judge like the description says to. I also managed to submit 4 star dishes to the judges during the monthly cook-off and they accepted it just like a regular contest. I just wonder if getting the book requires at least 4 star to each judge, and that judges in the monthly cook-off accept nothing less than 4 stars?

I do recall recently that the cooking values have changed to where what used to be a 5-star dish is now a 4-star dish. Many of my friends have had extreme difficulty of producing 5 star dishes since the update. I believe it was the G14S4 update that changed the percent values of a "perfect" or 5-star dish.

This is probably the best reason that you got the book.

You get the book either at the end of the Cook-off or after you finished the dishes. If it is your first time doing the cook-off, or you have rank 9 or below cooking, you will automatically receive the book from Gordon after submitting the 3 required dishes to each judge.

The judges have always accepted 4 or 5 star dishes.
