Why can a player's paintjob racquet differ from the retail model?

Try these steps in order

1. When reviewing equipment information, put wording from the manufacturer's official page, information directly confirmed by journalists or stringing teams, and photo-based estimates in separate columns. Sources that copy one another do not count as independent evidence. Separate the player racquet's paintjob name, claimed actual frame, weight, balance, swingweight, and claimed string and reference tension. If a value lacks a unit or measurement condition, or is described only as “about,” do not store it as confirmed.
2. A frame photograph may reveal the pattern and grommet shape, but it cannot establish the mold, layup, or internal customization. Do not infer the exact string and tension from the knot location alone. Put only the retail model's official specifications and actual demo measurements in your purchasing table. Keep player setups in a separate “why this is interesting” note instead of feeding them directly into candidate filters or suitability scores.
3. With each retail candidate strung alike, hit 20 crosscourt balls, 10 defensive balls, 10 returns, and 10 serves. Record average trajectory, late preparation, and late-session centered-contact rate. Judge whether the racquet solves your problem, not whether it feels like a player's. When sharing player information, attach the date and source and state the evidence level—for example, “appears to use that paintjob” or “the manufacturer says the equipment may differ”—rather than asserting “uses.” Revise estimates when new official information appears.
