• 1

  The Elo Rating Calculator applies the standard accepted formula to the values you enter, so the result is only as good as its inputs — fill every field in one consistent unit system and re-check any value copied from another source.

• 2

  Round only at the end: Elo Rating carries full precision internally, so rounding intermediate values by hand can shift the final answer more than the accuracy of the formula itself ever would.

• 3

  Read implausible results with suspicion: if the Elo Rating output sits orders of magnitude away from your expectation, re-read the inputs — a misplaced decimal or two swapped fields explains most nonsensical answers.

• Entering values in the wrong field is the top error on a Elo Rating page: adjacent inputs accept any number, so a swapped or shifted value still produces a plausible-looking result. Read each label against your data before calculating.

• Implausible inputs make worthless outputs: a result computed from estimates, brochure figures, or copied numbers inherits every one of their errors. Feed measured values into the Elo Rating, then sanity-check the output against a rough expectation.
