vso chart



I'm wondering if someone can help me. I have to transfer some old 78s to cd for someone and I don't have a turntable that plays 78's. I work in protools and was planning to record in at 1/2 speed playing at 33 1/3 or 45 rpm which would get me to within about 15% of the correct pitch. With some simple high school math I can figure out the % to vso playback,but my problem is varispeed is only displayed in musical notation on my system (cents). Many years ago in a land far away when everything was analog I remember having a chart that displayed pitch in both musical terms and %. Does anyone out their have anything like that they can email me or direct me to.

thanks in advance
