No, the answer is that is it repeats a million times. It might better be
Or put another way, myself and the OP misinterpreted what the call
t1.repeat( number = 1 ) did.
its a confusing API.
For the OP:
The call t1.timeit() is equivalent to t1.repeat( number = 1000000 ).
So it bennefits from memoization because the call *is* repeated, not
just called once like you intended.
