[argyllcms] Correcting Lab readings for paper white

I have made a set of Lab readings of a test chart. I am looking for a simple method that will help me correct the Lab values for the paper white.
I am looking for a mapping that would, for example, convert my paper white point from: 

97.51   0.78    -2.96 -> 100 0 0
I know I could try a roundtrip through the ICC profile I have calculated for this printer. I am afraid that this will introduce largish errors. 

I was wondering if anyone can suggest a simpler formula for the correction.
