The jubilismic equivalence continuum is a continuum of temperaments which equate a number of mothwellismas (99/98) with the jubilisma (50/49).

All temperaments in the continuum satisfy (99/89)n ~ 50/49. Varying n results in different temperaments listed in the table below. It converges to the 11-limit temperament of mothwellismic as n approaches infinity. If we allow non-integer and infinite n, the continuum describes the set of all 11-limit temperaments supported by undecimal jubilismic due to it being the unique temperament that tempers out both commas and thus tempers out all combinations of them. The just value of n is approximately 1.9899, and temperaments near this tend to be the most accurate ones.
