I entered the 200 IM at the 2005 Short course American Championships in Austin

I'd say this makes sense. Since there are the same number of turns in scm and scy you could just try multiplying by the meters to yards conversion factor. This would give 58.0 (63.49 * .9144). Of course, since you're swimming about 9% in further you need to consider that you'll go a little slower due to the additional distance. So this is the reason you add a little less per 100 for faster times.
