Speed Drop Explained for Putting

Speed Drop is not a number most golfers think about until a putting session makes it impossible to ignore. Once you understand what it is showing you, it becomes a useful shortcut for reading why a putt started where it did or why it rolled the way it rolled.

The goal is not to turn putting into a science project. The goal is to use one clean number to make your practice more honest and your misses easier to explain.

What Speed Drop Means

Percent speed loss from launch to roll start. In simple terms, the percentage drop in speed from Ball Speed to Roll Speed.

Why Golfers Should Care

Large drops can indicate inefficient launch/skid behavior.

Track this with skid distance to improve roll consistency.

How To Use Speed Drop During Practice

• Start on a simple, fairly flat putt so the number is easier to interpret.
• Use sets of putts, not one ball, to see whether the pattern is real.
• Pair it with launch and start-line numbers so you know whether the issue was delivery, skid, or read.

Common Mistakes

• Treating speed drop like the only answer. Putting numbers are most useful when they confirm what the start line and roll are already telling you.
• Ignoring pace. A good-looking stroke number does not help much if distance control is still off.

Do Not Read Speed Drop Alone

Speed Drop becomes much easier to trust when you read it next to Roll Speed, Roll %, Skid Distance. That combination tells you whether you are looking at delivery, launch, strike, or outcome.
