Unfortunately, Nicky has gone mad...
It may not be obvious to those who haven't paid attention to the latest updates and changes, but 50 is currently the Houtian limit. Beyond 50, it's already considered Pseudo Xiantian. As far as can be inferred, any increase of 10 points could very well mean something like 2 times stronger or more.
A practical example just to put it in proportion... If you remember the fight against the six from Havoc, one of them "summons" a giant dog or something like that, such an attack was "instant death" without high-level Dao to counter it, because it was something of the level "impossible for a Houtian to survive". Now, according to my friend's "inside information", with stats at 70 it doesn't even deal damage.
