Product Details

This is the only appraisal service in Japan that uses an analysis tool independently developed by an IT engineer with over 10 years of competitive experience to derive your correct answer from statistics and physical logic.

We are offering this service at a test operation price of 3,000 yen. The price will be revised to the regular price thereafter.

[Current Analysis & Improvement Measures Provided by This Diagnosis]
After purchase, we will compile a report covering the following based on the data you provide via message (grip strength, experience, current concerns, etc.).
(An example of the analysis results is shown in the product images.)

Current Analysis: Diagnoses the suitability of your current setup based on your muscle strength and play style.

[Identification of Cause]: Clarifies the cause of your current concerns with numerical evidence.

[Specific Improvement Points]: Provides concrete recommendations for optimal tension and suitable racket/string characteristics.

[Recommended Practice Menu]: Advises on practice methods to maximize your potential based on the analysis results.

[Difference from General AI and Online Information]
General AIs like ChatGPT only provide general theories applicable to anyone found online.

Strength of This Tool: Instead of AI making guesses with words, my independently developed physics simulation program directly calculates impact load and rebound efficiency from unchangeable facts such as your grip strength.

[Delivery Method (Completed by Mail)]
This service does not end with simply conveying the results on screen.
We will print the Detailed Diagnostic Report summarizing the analysis results and mail it to you via anonymous shipping (Rakuraku Mercari便).

[Flow After Purchase]
After purchase, please answer the questions in the transaction message.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
