other opponents matter, but they don't matter as much - because they are nowhere near as tough as stan playing well.
the one opponent who played well - murray , he was +8 against.
yes, djoko should've ended that match vs Murray sooner, but he didn't. That's the point - he wasn't that invincible as you make him it out to be.
The tough draw part only began from QF onwards, not before that.
For your reliance on the W/UE stats only , here's a shocker for you :
1. he was -7 vs Murray in AO 11 final ( 26 winners to 33 UEs) - a match he dominated.

2. he was -14 vs Murray in AO 13 final( 47 winners to 61 UEs) - he won it in 4 sets
(
The stats. The second serve and net points won are the telling ones, along with Djokovic's greater aggression.
Aces: Djokovic 8 Murray 7;
Double faults: Djokovic 3 Murray 5;
1st serve points won: Djokovic 75% Murray 81%;
2nd serve points won: Djokovic 66% Murray 46%;
Winners: Djokovic 47 Murray 29;
Errors: Djokovic 61 Murray 46;
Net points won: Djokovic 35 Murray 9;
Total points won: Djokovic 139 Murray 126.)

3. he was -10 vs Murray in AO 16 final ( 31 winners to 41 UEs) - he won it in straights.
So all of these were not decent performances ?
the winners or UEs are not the biggest component in a match. The forced errors are. Consider those.
Again, what you said is still not a response to the point about the AO encounters b/w djokovic and stan, where djokovic played well, wasn't passive and it still went 5 sets on both occasions ( 13, 14)
