It's not rocket science, in some instances people give advice on things that have worked for them with their personal dogs, problem, you don't own one of their dogs.
Trying different approaches is fine after proper time to see if any approach will work as you don't want training to be like a ping pong ball bouncing all over the place. Also I would not advise taking pain advice from online would be experts as that would be silly indeed.
