II. MEMORIZATION STRATEGY
The following is not intended to glorify or explain away his achievement; rather, it describes the daily pi practice that strengthens and refines his natural talent:
1. He memorizes digits in groups of ten.
2. He gradually increases the size of memorized groups, combining sets of ten digits until he can memorize 100 digits at a time.
3. He repeats this process for each subsequent set of 100 digits.
4. He practices and utilizes symmetry within small digit groups (e.g., 202, 9009, 03530).
5. He associates these small groups with colors in the visible spectrum, visualizing them as living and moving within his mind to help him see the digits.
6. He practices 30 minutes every day, reciting the first 5000 digits flawlessly before learning additional digits. The routine typically takes about 25 minutes for reciting the first 5000 digits and 5 minutes for learning new digits.
7. His motivation is to demonstrate the profound potential of human cognition and memory, particularly by highlighting the memory capacity of children.
8. He believes that memory is the fundamental architecture of thought. Without memory, knowledge cannot exist, as it requires storage and retention. Without knowledge, cognition cannot occur, because cognition is the processing and application of knowledge. His focus is not on chasing digits, but on developing his neural capacity to retain, process, and apply information.
9. His innate drive, disciplined practice, and deep motivation collectively exemplify how talent and training cultivate extraordinary memory capacity and cognitive ability.

III. PI VIDEO STANDARDS
1. 360° VIEW
To show that he was not using any concealed devices in his ears or on his body:
a) He rotated his body 360° to display all sides.
b) The camera zoomed in on both ears.
c) His video shows all angles from head to toe.
2. BLINDFOLDED
He was blindfolded to ensure the recitation was performed from memory.
3. CLOCK & STOPWATCH
Clock and stopwatch were embedded in the video, showing that the recording was conducted in real time, without alterations to speed or duration.
4. CONTINUITY
His recitation was recorded in a single, continuous video without cuts or interruptions.
5. FULL COUNT
His video includes the full count of all digits recited.
6. AUDIO CLARITY & LIP SYNC
His lip movements were perfectly synchronized with clear audio of every digit spoken.
7. VIDEO CLARITY
His video was recorded in 4K resolution, allowing viewers to zoom in on any part with clarity for detailed analysis.
8. AUTHENTICITY
His video is genuine and original. It has not been edited, altered, or generated by AI.
9. CONSISTENCY & PROGRESS
Like athletes in any sport, memory athletes require consistent training to achieve progress and set new records. He practices daily, and each time he memorizes an additional 100 digits, he records a new video reciting all digits from the beginning of pi (starting at 3.14). This results in a large archive of 112 videos on his YouTube channel, demonstrating his consistency and progress.
10. TRANSPARENCY
He insists on transparency and openly discloses his memorization strategy and progress.
11. ARCHIVE
He preserves his records for history.
12. TRUTH
Hero is raised with the motto, “No true hero is born from lies,” a principle that dictates true greatness cannot be achieved through deception.
Cheats are common, and genuine talent is rare. Many people claim to spend hours typing or writing thousands of digits or offer their memory methods in lengthy videos, yet avoid offering a recording of themselves orally reciting the digits.
He insists on video evidence, especially for something as precise and countable as orally reciting a specific number of pi digits.
He understands that the public has a strong interest in and right to evidence, particularly for extraordinary claims.
“What can be asserted without evidence can be dismissed without evidence,” and “extraordinary claims require extraordinary evidence.” Claims without proof deserve to be dismissed as dishonest or fraudulent.
Truth demands evidence; hence, he adheres to rigorous standards to ensure the public has the truth.
