🥏 Disc Golf Putting Probability Calculator

C1X (Circle 1 Extended) refers to putts from 10 to 11 meters (approximately 33–36 feet) from the basket. This is the narrow transitional zone just outside Circle 1 (which ends at 10m) and at the very start of Circle 2. PDGA and UDisc track C1X separately because these edge-of-circle putts are significantly harder than standard C1 putts but more makeable than deeper C2 attempts. For pros, C1X make rates typically range from 45–65%, while C1 overall is 85–92%.

For recreational and intermediate amateurs, a C1 putting percentage of 60–75% is solid. Advanced amateurs (MA1) often hit 70–85%. Elite pros consistently achieve 85–92% from C1. If you're below 50%, focus on shorter putts (3–5m) to build confidence and develop a repeatable putting stroke before extending your range. Tracking your stats by distance zone helps identify where you're losing strokes.

Putting probability follows an exponential decay curve. Most players maintain high accuracy inside 5 meters (70–95%), but the drop-off accelerates between 7–12 meters. By 15 meters (C2), even top pros make fewer than 1 in 3 attempts. The key factors are: distance perception, increased need for power (which reduces touch), wind effects, and mental pressure. Use the estimator slider above to see how probability changes at each distance for your skill level.

Tracking C1X separately gives you a clearer picture of your edge-range performance. Many players have a significant drop-off between 10m and 11m. If your C1% is 80% but your C1X% is only 20%, that reveals a specific weakness at the circle's edge. Similarly, a strong C1X% (40%+) indicates you're comfortable with the added distance and may have good C2 potential. It's a diagnostic metric that helps target practice.

Circle 2 (C2) covers putts from 11 meters to 33+ meters (approximately 36 to 108+ feet) from the basket. There's no upper limit—any putt beyond 11m is technically a C2 attempt. In practice, most C2 putts on the pro tour fall between 12–25 meters. Making even 20% of C2 putts is considered excellent at the pro level. For amateurs, C2 putts are low-percentage and should be approached with smart course management (sometimes laying up is the better play).

Key strategies:
① Structured practice: Use the tracker above to log 50–100 putts per session from specific distances. Track progress over weeks.
② Staggered distance drills: Practice putts at 8m, 9m, 10m, 11m, and 12m to gradually extend your range.
③ Video review: Film your putting stroke. Look for consistent release points and follow-through.
④ Spin putting: For C2 range, developing a spin putt (more velocity, flatter trajectory) can increase your make percentage compared to a pure push putt.
⑤ Mental game: Treat C1X/C2 putts as "bonus" opportunities. Reduce pressure by accepting that misses are expected at these ranges.

To compete at a 1000+ rated level, you typically need: C1: 84–90%, C1X: 48–60%, and C2: 22–32%. However, putting is just one component. Players like Paul McBeth and Ricky Wysocki separate themselves with elite C2 putting (often 30%+) and clutch C1X performance under pressure. The PDGA ratings system weighs all aspects of play, but strokes gained from putting—especially from C1X and C2—are a massive differentiator at the highest level.

There's no one-size-fits-all answer. Push putts excel inside C1 (0–10m) due to their consistency and soft landing. Spin putts generate more velocity and can be more effective from C1X and C2 distances, as they maintain a flatter trajectory and reach the basket faster (less affected by wind). Many elite players use a hybrid "spush" putt—a push putt with added spin—for the 10–15m range. Experiment with both styles and track your percentages by distance to find what works for you.

Wind can dramatically reduce putting accuracy, especially beyond 8 meters. A 10–15 mph headwind can lower C1X make probability by 15–25 percentage points. Crosswinds are even trickier, pushing the disc off its intended line. Tailwinds can help carry the disc but may cause it to sail past the basket. Pro tip: In windy conditions, aim for a slightly lower release and use a more stable putter. Also, adjust your expectations—a 30% C1X day in strong wind might actually be solid play.

Yes! The probability curves and benchmark percentages are derived from publicly available PDGA tour statistics and UDisc Live data from professional events. The amateur estimates are based on survey data from the disc golf community and typical MA1/MA2 tournament performance. While individual results vary, the curves provide a realistic baseline for setting goals and tracking improvement. Use the stats tracker to see where you fit relative to these benchmarks.
