Onsite Paddle Testing Is Expanding. Here’s What Players Should Know.

Imagine showing up to a tournament with a paddle you know is legal… only to be told it suddenly fails onsite testing. 

As onsite paddle testing begins rolling out across amateur pickleball events globally, situations like this are becoming increasingly common. 

At Six Zero, we support efforts that improve fairness and consistency in competitive pickleball. If onsite testing can help create a better experience for players, that’s ultimately a positive step for the sport. 

But right now, the process is still evolving, and there are several major inconsistencies players, organizers, and manufacturers should understand. 

Our goal with this article is simple: explain where things currently stand, what challenges still exist, and why clearer standards are important as onsite testing expands. 

The Main Issue: There Isn’t One Unified Testing Standard 

At the moment, the UPA and USAP use different testing systems, equipment, and pass/fail standards. 

That matters because a paddle can potentially receive different results depending on: 

USAP is still actively developing and trialing portions of its onsite testing process, while the UPA has its own separate procedures and approved equipment. 

From our own testing, we’ve observed meaningful differences between some onsite test results and controlled laboratory results, particularly relating to: 

For players, this can create confusion around what is actually considered legal at a given event. 

Our internal lab testing indicates a non-linear relationship between UPA and USAP deflection tests. 

Why Deflection Testing Has Become Complicated 

One of the primary tools currently recommended by the UPA for onsite testing is the Pickle Pro Labs Go/No Go deflection machine. 

Through both internal testing and real-world event observations, we’ve identified two key challenges with the current process. 

1. Temperature Can Affect Results 

We’ve seen the same paddle produce noticeably different readings depending on ambient temperature conditions. 

For example: 

That variability becomes important when a paddle is being judged against a strict pass/fail threshold onsite. 

2. The “42 Rule” Is No Longer Universal 

Historically, many players and tournament staff operated under the assumption that a deflection reading of 42 was the universal pass/fail benchmark. 

That is no longer the case. 

The UPA has updated its guidelines so that approved paddles can now have their own individual pass/fail limits. 

The problem is that not all events appear fully updated on these changes yet. 

We’ve already seen examples where older universal standards were still being applied, creating situations where legal paddles risk being incorrectly flagged. 

The Bigger Problem: UPA and USAP Standards Don’t Translate Cleanly 

Another growing challenge is the use of UPA testing equipment at USAP-sanctioned events. 

Currently: 

Our internal testing continues to show that a paddle can record: 

In practical terms, this means a paddle could potentially: 

That creates difficult questions for tournament organizers: 

At the moment, there still isn’t complete alignment across the sport. 

Example #1: Las Vegas Golden Ticket Event 

One recent example involved a paddle that reportedly failed onsite COF testing at the Las Vegas Golden Ticket event using equipment currently being trialed by USAP. 

The onsite reading recorded was: 

That result immediately stood out to us because we had never previously seen a reading anywhere near that level on one of our paddles. 

The paddle owner then sent the paddle to us for additional testing using our certified laboratory COF equipment. 

Our lab produced replicate readings of: 

Those results were dramatically different from the original onsite reading. 

We are currently in communication with USAP regarding these findings and the broader challenges surrounding onsite testing consistency. 

USAP onsite COF machine - result is an order of magnitude higher than what we tested on the exact same paddle in the our lab using a certified lab COF testing unit. 

Example #2: Amateur Event in Australia 

A second example came from a recent amateur tournament in Australia that allowed both UPA and USAP approved paddles but only used a UPA Go/No Go machine onsite. 

Several issues became apparent: 

Our own testing continues to show that some paddles can record: 

This is exactly why applying a single universal onsite standard across different governing body certifications can create inaccurate outcomes. 

 The same paddles produced significantly different Go/No Go deflection readings depending on cooler morning versus warmer daytime conditions.  Event staff were unaware of the updated UPA paddle-specific pass/fail benchmarks.  The machine was also being used to evaluate USAP-approved paddles based on the outdated assumption that 42 remained a universal standard. 

What This Means for Players 

For players, the current environment can feel confusing. 

A paddle may: 

That uncertainty is why we believe the sport still needs: 

Our Position Moving Forward 

We believe onsite testing can absolutely improve competitive fairness if implemented correctly. 

But for the system to work consistently across the sport, the process needs to become: 

As a manufacturer, our responsibility is to continue testing rigorously, communicate openly, and advocate for standards that are accurate and fair for players.
