Can't comment on your accurate HD speedo, but most mfgs build-in optimistic speedos because by various national vehicle certification standards, it is illegal to build a speedo that reads too low. So to provide them a "fudge factor" to cover tolerances, different tire sizes, etc., they by design build them to read 5% high. So blame the safetycrats and lawyers.
