Section 3.3.3 says:

evaluatedElement = G.ScalarInverse(t) * blindedElement

It should say:

evaluatedElement = t * blindedElement

Notes:

This appears in def BlindEvaluate(skS, blindedElement, info). It seems that the evaluatedElement=t * blindedElement, which is consistent with tweakedKey = t * G.Generator()
