At European Championships the Rings panel had SmartRings v6 software. It’s developed in Netherlands.
Deductions for strength hold flagged by that software were shown as extra deductions not included in the E-score.
I did see several occasions where the panel double checked the software by watching the video after the routine was finished. Perhaps it’s not foolproof yet.
Nobody I’ve spoken with knows exactly how it works. GBR coach Lee Woolls did post this.
