here's a great example of how the JI version of HEWM

differs from the 72edo version (the 72edo simplifies things):

say i want to find the notation for the ratio 42:25,

assuming that C = 1/1.

the first thing to do on the spreadsheet is to make

sure that there's a zero next to "C" in the column

of cyan cells near the top. this defines "C" as 1/1.

then put in the target ratio. whether using the method

of inputting "comma" exponents or inputting the notation

directly, the result will be the same:

2 3 5 7 11

target ratio: [ 1 1 -2 1 0] 42/25 898.2

HEWM: B bb - [ 15 -9 0 0 0] 32768/19683 882.4

-------------------

[-14 10 -2 1 0] 413343/409600 15.7

< - [ -6 2 0 1 0] 63/64 -27.3

-------------------

[ -8 8 -2 0 0] 6561/6400 43.0

+ - [ -4 4 -1 0 0] 81/80 21.5

-------------------

[ -4 4 -1 0 0] 81/80 21.5

+ - [ -4 4 -1 0 0] 81/80 21.5

-------------------

[ 0 0 0 0 0] 1/1 0.0

so the JI HEWM notation for 42:25 is Bbb<++.

this is simplified in 72edo, because in 72edo, < = --

and > = ++, so we have Bbb<>, and the <> cancel each

other out, leaving us with just Bbb.

in the JI version of HEWM, > and ++ are not the same.
