 There is likely overhead in capturing hardware counters, so these should be more "correct"
 
-NOTE - MWC256 is likely poorly implemented (it is supposed to be faster). As seen in the instrumented benchmark below there are a lot of branch mispredictions.
-This is clear from the generated assembly atm but I'm not sure why those branching instructions are generated. `UInt128` support is pretty new
-so maybe there are some inefficiencies there.
