At which point did you feel Djokovic's massive decline was irreversible?

[Tennisgods]

Can’t write him off at this point, far too early into a comeback. Give him a few solid months on tour at least to see what he does. At the moment, he’s lacking in strength, trying to test the elbow in match play and very rusty.

I actually think he’s doing himself no favours by bombarding social media with all the “i’m coming back!” vids and pics. That’s all fine if you back it up.

But yesterday was not backing it up!

He should be playing it cool at this point, be realistic with his fans expectations.

When he decides to retire, then it's irreversible.
When Gumby is no longer pliable, then it's irreversible.

He served faster than 2016 according to the match graphics...the game and players evolve...TARO is a great player...he took a set and was up a break in the second set against RAFA at the USO 2017...would have won that If it wasn't for the 5 setter in the first round...

GOATaro?

This is called “Begging the question”, a.k.a. petitio principii: One of the fallacies types, which basically implies providing what is essentially the conclusion of the argument as a premise.

EXACTLY. The classic case of this is asking a random guy: “When did you stop beating your dog?”
