2020 was his rookie season and I looked back to see what his RTs were, on the theory that ‘something’ magic was found in the last few years by him or a crew member. Well… he was just as good from the get-go. Hardly ever had worse than .060s and many below .050. Including a .001 at Indy, a .017 and .020 at other events etc. Not sure if crew changed since then but now makes me think it’s all him.
