"optimum time..."

Does it sound natural to say 'the optimum time is at least 1 week'?

I am describing the optimum length of time needed to obtain a noticeable result.

Thanks

It is natural English in terms of sentence construction, and would pass I guess. But, being picky, "optimum" to me usually suggests a maximum, or peak, with the desirability of the outcome dropping off when any parameter is adjusted in any direction. So, "the optimum time is one to two weeks" would IMO be a more standard use of "optimum".

  • An open-ended optimum ("at least") doesn't feel quite so right to me.
