If the Lucario has Inner Focus, it would be +2 Attack. If the Lucario has Justified/Steadfast, put +1 Attack (Inner Focus blocks Intimidate). So that’s that. Attack gets lowered one stage then raised by 2 stages, so +1.
I don’t know if you can see the exact number, but you can definitely see the difference in the calculations.
252 SpA Tapu Lele Energy Ball vs. 4 HP / 0 SpD Tyranitar in Sand: 132-156 (38.5 - 45.6%) -- guaranteed 3HKO
252 SpA Tapu Lele Energy Ball vs. 4 HP / 0 SpD Tyranitar: 198-234 (57.8 - 68.4%) -- guaranteed 2HKO
So, you can see that the special defense clearly raises, but I haven’t found a way to see the exact number of a stat after boosts or with special conditions like rock types in the sand. I will say, the stat multiplies, so you can take the stat and multiply it by 1.5, 2.0, 2.5, 3.0, 3.5, and 4.0 (1.5 is +1, 2.0 is +2, 2.5 is +3, etc.)
Just keep lowering the special attack by two stages, each time you calculate a Draco Meteor. So the second one would be from -2, the third one will be from -4, and the fourth one will be from -6. Next to a stat, you can lower/raise it by 1-6 stages.
Intimidate would be -1 Attack, since it lowers Attack by 1 stage.
Close Combat you would put -1 Defense and -1 Special Defense.
Sticky Web you would put -1 Speed.
For Special Attack after Draco Meteor, put -2 Special Attack.
Hope this helps! :)
