Since 209 factors into {{factorization|209}}, 209edt has [[11edt]] and [[19edt]] as subsets; it inherits its mapping of the 11th harmonic from the former and the 17th from the latter. It otherwise represents a very strong system in the [[19-limit]] (even including prime 2), being the sum of [[78edt]] which has a flat tendency in the 19-limit and [[131edt]] which has a slight sharp tendency. Its most accurate simple intervals are [[7/5]], [[11/5]], and [[17/9]], all of which it approximates to within about 0.1 cents.

It otherwise represents a very strong system in the [[19-limit]] (even including prime 2), being the sum of [[78edt]] which has a flat tendency in the 19-limit and [[131edt]] which has a slight sharp tendency.
