An actual run · a synthetic answer
The calculation is wrong. Why did it score 82?
This answer has numbered steps, asks the reader to check the data, and states a limitation. It looks thorough. But the first step gets relative growth wrong.
“conversion rose from 20% to 30%, a relative increase of 10%, according to [1].”
Subtract the starting rate and you get 10 percentage points. Divide that increase by the original 20%, and relative growth is 50%.
(30% − 20%) ÷ 20% = 50%
The tool gave the full English answer 82/100. It asked for sources but did not identify the arithmetic error. [1] has no corresponding reference, yet counted as citation formatting; steps, verification words, and caveats added points.
That is where this checker helps—and where it misses things. It can find text signals; the calculations and citations still need checking.

1. First record the metric: conversion rose from 20% to 30%, a relative increase of 10%, according to [1].
2. Then check the starting and ending values in the file, for example by keeping the original counts and observation window for the same group.
3. Finally state the limitation: these are synthetic numbers, and other groups may differ; verify the denominator and sampling method, and preserve the calculation and source in the report.
