There is little doubt, nevertheless, that he had an unusual level of influence with the King until the Lauder coup of 1482. In a highly unusual practice, he is found countersigning royal letters regularly in the later 1470s. After the coup, he was briefly disgraced, and although he was restored to favour after the king regained power in 1483, his influence was not what it had been.
His influence over the King was substantial until the Lauder coup of 1482, after which it diminished significantly. He was a frequent signer of royal letters during the late 1470s but lost favor and prestige following the coup.  Although he was reinstated in 1483 when the king regained power, his influence did not return to its previous level.
