When stock is empty, turn the whole waste over without shuffling. Draw One exposes the earliest remaining waste card first. If you move no cards and change nothing else, another full pass offers the same cards in the same order.
Worked example
Waste contains 4 of clubs underneath 6 of diamonds. Recycle it. The next draw exposes 4 of clubs; another draw covers it with 6 of diamonds. With neither card moved, you reach the same visible arrangement again.
A Legal Action Is Not a Winning Plan
The pictured column ends in black 5 of spades. Black 4 of clubs cannot go onto it: the colors match. Red 6 of diamonds cannot go onto it either: the rank goes up, not down. Recycling is still a legal action. That does not prove it helps. Inspect the other columns and foundations before making a claim about the whole deal. S3U also permits a foundation top card to return to a legal column.
