Robinson remarkably said "shape is for pundits" in one interview as Aberdeen toiled at the start of the campaign while playing 4-3-3.
Since then, the Northern Irishman has gone back to using three centre-backs and two strikers, a system which brought him consistent success at St Mirren.
The effect has been clear to see. Aberdeen are more solid, better at pressing, and look a threat when breaking forward given the pace they have up front.
Centre-back Mats Knoester and midfielder Afeez Aremu have been transformational in recent games.
The former is by far the club's best defender, while Aremu gets all over the pitch and wins the ball before playing simple passes to get moves going.
For all Hibs' second-half play, it will anger the Aberdeen boss that a silly challenge from Milne ultimately cost his side three points, after Nisbet's excellent touch, turn, and finish put them in front.
It was the third game in a row the striker has scored in, and there are lingering questions about who else will contribute to the Aberdeen tally this season.
But after a torrid start, Robinson will be content that he is starting to build the foundations for a more promising season.
