In episode 18 of GolfCask, Brian Bailie dives into the "DNA of Golf," comparing it to the previous whiskey episode on grain to glass. He breaks down the key factors for improving golf performance based on shooting scores, from 90s to par or better. For players shooting in the 90s, he emphasizes controlling lateral dispersion, targeting within certain finger distances, and improving shots to the green. As players progress into the 80s and 70s, dispersion tightens, and the focus shifts more to ball striking, short game, and putting. Par or better players excel with tighter dispersion, more greens in regulation, and higher scrambling and one-putt percentages. Brian also highlights upcoming content on Golf High IQ, emphasizing the importance of better training, and invites listeners to the Irons and Oak event in December.
