In this episode of On The Mark, host Mark Immelman welcomes back Cordie Walker (last on the show in 2019) for a practical, no-fluff conversation on what actually moves the needle for your golf game: Speed Training with intent, how to make Real Swing Changes, Practice Structure, Course Management using Dispersion, and Wedge Gapping that holds up under pressure. 

Cordie shares his journey chasing 180 → 190 → 200mph Ball Speed, why most golfers “speed train” the wrong way, and how dedicated sessions (with a real warmup and real volume) raise your floor, not just your ceiling.

Then the conversation pivots into improvement that transfers: Get Better Feedback (video + data), Practice with a Purpose (technique vs skill vs performance), and build a Wedge System that makes “shot #3” a weapon. 

In This Episode, You’ll Learn:

• Why “intent” is the missing ingredient in most speed training (and what a real session looks like) 
• The #1 speed-training sign you’re actually going hard enough (yes—it should feel out of control) 
• How video changes everything: what you feel vs what you actually do 
• Why swing changes are harder than golfers think—and what it really takes to make them stick 
• A simple practice framework: Technique vs Skill vs Performance (and why most practice fails) 
• How great course management can free you up (and when “send it” actually makes sense) 
• Why dispersion is a shotgun pattern, not a “rifle”—and how to use it to play smarter, and
• A wedge gapping starting point most golfers skip (and why it’s killing your scoring.)

Key Takeaways:

1. Speed is trainable—if you train it on purpose. Dedicated sessions, real warmup, and enough volume matter.
2. Feedback is everything. Video + launch monitor data keep you honest and accelerate change.
3. Practice needs a goal. Decide if you’re working on technique, skill, or performance—then practice accordingly.
4. Course management isn’t “play scared.” Know your dispersion and make emotionless decisions—then commit.
5. Wedge gapping wins tournaments for regular golfers. Build baselines, stop swinging wedges too hard, and refine.
