Yes. +10% poly to multi, +10% or so multi to gut (depends on which gut).
So, starting at 47, my first guess would be 57 lbs. Go up or down from there depending on what you like/don't like about the stringbed.
For a 98sqin racket, I'd go to mid-60's for gut and it would feel comfortable and powerful, but I'm about 5 lbs higher on my poly tensions. Don't be afraid to go higher than the initial 57 if you want more control, it will still be powerful and comfortable in the 60's. (Some guts break a lot at higher tensions, so if you go much over 57, you will have to get a high quality gut.)
One should be careful with going OVER 62 pounds for 17 gauge (even with Wilson 17 gauge).
