Let a Level 1 job consist of doing tasks "foo", "bar" and "bash" on a daily basis.

Let Level 2 tasks consist of doing "aleph", "zeta" but also sometimes a little "foo".

Some L1 employee killing it in terms of time-taken-to-complete bars and bashes, as well as being solid at foo...

Is not the same as

Some L1 employee is [okay to above average] at their regular job responsibilities (foo, bar and bash) and every now and then handles aleph and zeta without trouble (and sometimes excels at it).
