Opposite edges

Opposite edges is a PLL parity case on the 4x4 (easy). Algorithm: 2R2 U2 2R2 Uw2 2R2 2U2. Below are 2 variants with a 3D animation and a scramble to practise.

My Reminder
My status:don’t know
How the status is counted

Training counts the status. A case added to training gets “learning”, and “known” after 5× “correct” in a row with the timer and without hints, when the average time is within the category threshold (Settings). 2× “wrong” in the last 3 attempts or much slower times drop it back to “learning”. Daily tasks don’t change the status.

How to recognize

Two opposite edges (front and back) are swapped, the rest of the last layer is solved.
