How to use this calculator
- Enter the number of problems in the round.
- Estimate tops and zones without exceeding the problem count.
- Enter total attempts across all problems.
- Add field size and calculate the model projection.

Climbing Grade Race Prediction Calculator
Project an indoor climbing competition round from expected tops, zones, attempts, and field size. Since event formats differ, this tool uses a transparent configurable-style points model rather than claiming to reproduce a particular federation rulebook. It estimates round points, completion rate, and a broad placement band. Check the organizer’s scoring rules before using the result for an actual event strategy.
Calculator
Expected competition roundFormula
Round points = tops × 100 + zones × 25 − max(0, attempts − tops) × 2
Placement percentile model = clamp(round points ÷ maximum modeled points, 0, 1).
What the result means
The score rewards tops first, zones second, and fewer unsuccessful attempts. The placement band is only a scenario indicator because field strength and official ranking rules are unknown.
“Race prediction” here means a competition-round scenario, not an official result forecast. Use the event’s published scoring and tie-break rules.
Example calculation
For 5 problems, 3 tops, 4 zones, and 9 attempts, the model gives 388 points, a 60% top rate, and 3.0 attempts per top.
Tips for better results
- Build conservative, likely, and optimistic scenarios.
- Model attempts honestly; repeated tries can affect ties.
- Check whether the event uses zones, bonuses, time, or countback.
- Plan early attempts around high-probability points.
- Do not infer exact placement from an unknown field.
Frequently asked questions
Does this match IFSC bouldering scoring?
No. It is a transparent scenario model and may not match current IFSC or local event rules.
Can zones exceed tops?
Yes, but neither tops nor zones can exceed the number of problems in this calculator.
Why is placement shown as a band?
Exact placement requires every competitor’s results and the event’s tie-break rules.
What if I expect zero tops?
The calculator still scores expected zones and reports attempts per top as not available.
Should total attempts include unsuccessful tries?
Yes. Enter all scoring attempts you expect to make across the round.
