Motor Service Factor Question

I have a typical motor that can be wired for 230/460 but is also rated for 208VAC operation. It has a typical 1.15 service factor. If I wire this motor to a 208V feed, can I still set the overload to FLA (@208v) x 1.15? It would seem to me that powering with 208V, which is 10% less than 230V, should effectively reduce the service factor.

Thanks in advance!
