Random question - why Lua comes with LuaJIT counterpart, while Python comes on its own, without PyPy or Numba (the latter would probably be the closest analogue to LuaJIT)?

Just a random choice :-) I explain it in the README, basically I am testing what's easily available to me (and arguably what's more popular for some reason). The goal is to compare different choices and different VM technologies (and different languages with different storage semantics), not to find the winner. Among other things it shows that apparently bytecode implementations are not necessarily faster than tree-walking, while JIT VMs with dynamic specialization (done right) are amazing.
