I would say that table is really quite valuable. Kaggle problems come from all types of companies, so it doesn't make sense to say that it is "overfitted patterns that he's adopted in his own realm". With that said, validation on your own dataset will trump general knowledge, so you shouldn't view these parameters as hard and fast rules. But the parameters in that table will provide a useful starting point, and if you stray too far from them that is a warning sign that you might be overfitting.
