Theory
419edo is a decent 7-limit system, and is consistent to the 9-odd-limit. The equal temperament tempers out 32805/32768 (schisma) in the 5-limit; 235298/234375 (triwellisma), 420175/419904 (wizma) in the 7-limit. It supports and provides the optimal patent val for sextilififths, the 130 & 289 temperament, in the 7-limit.
Extending it to the 11-limit requires choosing which mapping one wants to use, as both are nearly equally far off the mark. Using the 419e val, it tempers out 3025/3024, 5632/5625, and 8019/8000. Using the patent val, it tempers out 441/440, 4000/3993, and 14700/14641 in the 11-limit. The patent val supports 11-limit sextilififths, though 289edo is better suited for that purpose.
The same can be said of the mapping for 13, with the 419e val tempering out 676/675, 1716/1715, 4225/4224, and 4459/4455, and the 419f val tempering out 729/728, 2200/2197, 2205/2197, 3584/3575, and 4459/4455.
