a) proper alignments:
| 2) | depth - major arm fully extended (not hyper-extended) |
| 1) | hand - horizontal (palm facing ground) |
| 2) | wrist kept straight (not bent up / down and / or side-to-side) |
| 3) | elbow directly in-line with fist |
| 5) | upper body / hips - Forward Bow rotation |
| 6) | legs / feet - Forward Bow rotation |
| iii) | Point of Contact - index / middle / ring finger middle-knuckles (avoid pinky knuckle) |
b) proper formation - weapon (hand):
| 1) | all bent at middle and upper knuckle joints |
| 2) | kept together (compact unit) |
| 1) | pressed tightly against rest of hand (Compact Unit) |
| 3) | not tucked forward onto palm |
c) execution:
| i) | proper Method of Execution - Snapping |
| ii) | improper execution - not at proper speeds / methods: |
| 1) | executed too slow (transforms into push with knuckles) |
| 2) | executed too fast (stance rotation unable to keep up with strike) |
| 3) | executed too tense (unable to achieve proper 'snap' of strike) (strike looks 'pushed' out) |
| 4) | strike not tensed at Point of Contact (improper timing / never tensed) |
