dunedinPACE is interesting.  My first result was 0.78, which is 0.02 greater than yours.  When I did the trudiagnostic test I was given an extrinsic age and an old algorithm intrinsic age.  Did you have these?  My extrinsic was 47 and old algorithm intrinsic 43 (I am 63), my new algorithm intrinsic, however, was 62 (almost 63).
