Relative Time Severity Calculator

Compare actual time to optimal time using logarithmic scale

Relative Time Severity Calculator

Calculate the Relative Time Severity to compare actual time to optimal:

ext{TSS} = log_{10}left( rac{ ext{TV}(S)}{ ext{TV}^*(S)} ight)

Relative Time Severity:
Baseline (≤2×) Moderate (≈5×) Major (≈10×) Severe (≈25×) Crisis (≥100×)

Understanding TSS

Relative Time Severity (TSS) quantifies waste as an order of magnitude by comparing what is to what should be.

Each full point on the log scale represents an order of magnitude in wasted life:

Tier Approx. Overhead Meaning
Baseline ≤ 2× Tolerable variance
Moderate ≈ 5× Needs redesign
Major ≈ 10× Systemic failure begins
Severe ≈ 25× Chronic exploitation
Crisis ≥ 100× Mass Time Violence
