Biomechanics & Muscle Memory Tips
- 1Always use opposite-hand Shift alternation for brackets ({}, [], ()) so your right pinky never strains alone.
- 2Return your right index finger back to J immediately after hitting number-row operators like =, +, or *.
- 3Prioritize 98%+ accuracy on indentation and closing delimiters—backspacing syntax mistakes destroys Net WPM.
