New unit test fixes

New unit test fixes following sentences
He runs more often than John.
He runs less often than John.
He runs here more often than John.
He runs here less often than John.
He is faster than John.

What is "often" trying to solve here?  We also "He runs more frequently than John", should frequently be added?  What about "He runs more seriously than John?"  (a lot of sportsmen are serious, and don't joke around) "He runs more smartly than John?"  (don't know about running, but swimming takes brains. You can't swim fast if you're stupid) "He runs more quietly than John?" (spies sneaking around...) etc... He runs more ridiculously than John (Monty Python comedy sketch)

In short, having "often" here seems like the wrong solution to whatever the problem is...
