Each telic comma has a numerical range in which it can possibly be telic, that is, a '''telicity range'''. The size of a comma's telicity range is inversely correlated to the size of the comma itself – that is, the smaller the comma in question, the larger the size of that comma's telicity range. The size of a comma's telicity range is evaluated by comparing the size of a given EDO's step with the size of the comma in question – if the comma is more than half the size of the EDO's step, said EDO is outside the comma's telicity range. For example, [[81/80]] has a telicity range of 27, as 27 is the largest EDO with a step size that is more than twice the size of the comma, while [[Mercator's comma]] has a telicity range of 165, as 165 is the largest EDO with a step size that is more that twice the size of that comma. In addition, the concept of telicity can be used to evaluate the usefulness of EDOs relative to the [http://musictheory.zentral.zone/huntsystem2.html#2 JND] of human pitch perception, and, since an interval smaller than 3.5 cents is unlikely to be noticed by even the most trained listeners, it can be said that the JND has a telicity range of 171, meaning that EDOs that are higher than [[171edo|171]] are not all that suitable for use as musical systems outside of pitch bends.

It should also be noted that while the tempering of a given comma that is larger than half a step in a given EDO can sometimes be accomplished to join primes without either prime exceeding the 50% relative error threshold in said EDO, the fact remains that the EDO in question lies outside the comma's telicity range. Thus, such a phenomenon in relation to telicity is analyzed as being a result of the EDO in question tempering out two or more commas that actually do meet the strict criteria requirements, and thus, having two or more forms of the same type of telicity. As an example, 31edo tempers out 81/80, which is larger than half of this EDO's step size, but this can be attributed to 31edo tempering out both the [[Würschmidt comma]] (393216/390625) and the [[Semicomma]] (2109375/2097152), with the former equating an octave-reduced chain of eight [[5/4]] intervals with [[3/2]], and the latter equating an octave-reduced chain of seven 5/4 intervals with [[32/27]], while both commas additionally satisfy for telicity on account of being less than half an EDO step in size.
