Climbing Grade Recovery Needs Estimator

1. Enter the climb difficulty
Use your established numeric grade index so session comparisons stay consistent.

2. Count hard attempts
Include attempts that significantly loaded fingers, forearms, or pulling muscles.

3. Add recent sleep
Enter the hours slept during the previous night.

4. Rate local soreness
Use a 0–10 rating for ordinary finger and forearm training soreness.

5. Plan the next hard session
Use the score and suggested window as one input alongside pain, skin condition, motivation, and actual movement quality.

Workload = (Grade index ÷ 40) × Hard attempts × 5Sleep modifier = clamp[1 + (7.5 − Sleep hours) × 0.08, 0.80, 1.35]Recovery score = clamp[Workload × Sleep modifier + Soreness × 4, 0, 100]Suggested hours = round(16 + Recovery score × 0.55)

Where:

• Grade index = normalized climbing difficulty from 1 to 40
• Hard attempts = demanding attempts in the recent session
• Sleep hours = hours slept last night
• Soreness = ordinary finger/forearm soreness from 0 to 10

Assumptions: The model emphasizes hard attempts and local soreness. It cannot distinguish normal training soreness from an injury.

What the result means

The moderate-to-high recovery need is driven by both difficult attempts and noticeable local soreness.

This calculator provides an estimate for planning and comparison; real-world outcomes can vary with conditions and individual factors.

Given:

• Grade index = 24
• Hard attempts = 10
• Sleep = 7 hours
• Soreness = 5/10

Calculation:
Workload = (24 ÷ 40) × 10 × 5 = 30.0
Sleep modifier = 1 + (7.5 − 7) × 0.08 = 1.04
Recovery score = 30.0 × 1.04 + 5 × 4 = 51.2
Suggested hours = round(16 + 51.2 × 0.55) = 44 hours

Result: 51/100, with about 44 hours suggested.

Interpretation: The moderate-to-high recovery need is driven by both difficult attempts and noticeable local soreness.
