So, your arguments were no different from before, as I noticed.
Now, I'll really show you why you're biased :
Let's say that you're right and that in DBS, Goku can't be stronger (though I have evidence why this interpretation is obviously wrong). Now, let's argue for what really matters : the 5 years before DBS. If the training was ineffective in the first place, why did he continue to train even in the actual show ? Because it's fun to train for nothing in 5 years ? And Goku stated that he'd train to make sure that this time, he won't lose to Kid Boo. So he clearly trained to become stronger in the 5 years.
Goku (DBS) > Goku (Boo), you no longer can deny it.
