First, that string should have 28 strands. If two are cut then they are out of the equation. That string is sufficient for a 225 lb bow. A 200 lb bow is 1/8th less tension but the string has lost much less than that (1/7th) so mathematically I could say yes it is ok but if it really only started out with 23 strands then it is not usable. Bottom line? Get another string.
