There are three kinds of recency relationships between entries, used and used, used and unused, and unused and unused. However, LRU and Clock violate some recency. True LRU outperforms LRU and Clock by observing all recency.
The fundamental error is that new entries are considered most recently used. In fact, they have never been used in the cache. Therefore, new entries must to be added after the entries actually used.
Sequence: 1, 2, 3, 3, 2, 4
LRU
MRU |4 2 3 1| LRU
Hit |0 1 1 0|
^ Violation of the recency between used and unused.
Clock
N-1 |4 3 2 1| 0
Hit |0 1 1 0|
^ Violation of the recency between used and used.
True LRU
MRU |2 3 4 1| LRU
Hit |1 1 0 0|
^ ^ ^ Ideal recency.I have heard that sometimes the submission time is reset, such as when returning from the second chance pool. This could also create an unnatural ranking order, so the original time before the reset should be listed as well.

Too different from the title. And the other comments seem to have been written without reading the text.
Same in every field.

You clearly have no expertise in this field. Over.
If you only read one paper in an unfamiliar field, you will not know if it lacks the necessary analysis.
