It does show it with the number next to the language

Nope.

Language A programs can be implemented in language B without being "independently written".

1.zig may have been based on 9.rs.

Additionally, there are multiple reasons why one programming language might have nine different programs:

-The programs could have been written by someone who prefers to make small iterations and perform many submissions instead of someone who likes to make bigger changes with fewer submissions.

-The programs could be submitted by a novice who needs to make more submissions than would be required by a pro.

-The programming language may be older and has had more submissions.

-The programming language may be more actively changing and requires more updates in order to fix old programs.

-The programmers may also be making more submissions to improve other characteristics like memory usage, code size, code readability, compatibility, etc... that are unrelated to performance.

In short, previously the benchmarks game explicitly stated that the program numbers were arbitrary and signified nothing; and the same reasoning applies to hanabi1224's website.
