Ups-and-Downs-based notation: dublift and dubdrop

Another system proposed by [[User:TallKite|TallKite]] involves simpler notation, with as few extra accidental pairs as possible.  One could do with only one extra pair, only ups and downs (that is, darts), but one would need at least septuple ups, and in practice octuple or more, rendering such a system impractical. As a result, this system has two extra pairs of accidentals.

According to this system, 159edo would be notated with a combination of ups/downs and lifts/drops. The latter (referred to as "slants" here) are written / and \. The ups and downs are used as in 53edo, so one up is 3 edosteps. One lift is 1 edostep. Double-darts are dup and dud. Triple-darts are trup and trud.

Notes flatter than natural can be deduced by symmetry, i.e. C \C v/C vC v\C etc. Notes beyond sharp just run through the same list, but adding "sharp":
