Quite simply:
What isn’t understood on all 4 won’t be done against the wall.
What isn’t nailed on the wall will hardly exist reliably without it.
Unsurprisingly,
Freestanding > Wall drill > Floor drill
The more you can ingrain motor patterns and sensations on all 4 and with the wall, and the easier your life will be tomorrow: you won’t be surprised by anything, as all the pieces of the puzzle will have been covered.
The first stack is the foundation of your handstand. Without it, not handstand.
Make sure you revisit where it is every.single.time you warm-up.
