The Claim
One year of resistance training experience does not ensure accurate 0RIR prediction ability, as demonstrated by consistent underestimation across both experiments involving 38 total participants performing knee extensions.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Even if you've been lifting weights for a year, you might still not be good at guessing how many reps you have left in the tank, because people in a study kept thinking they could do more than they actually could.

What the research says
1 studyStudy: “Just One More Rep!” – Ability to Predict Proximity to Task Failure in Resistance Trained Persons
The study shows that even after a year of weight training, people still can't accurately guess when they're about to fail a lift, which matches the claim.
