Writing a pattern

I was wondering how you would write this - looking for the most comprehensible, yet simplest way…

my pattern (shawl) has 4 basic rows

row 1 and 3 has a specific sequence that is repeated
row 2 and 4 are simply purls

I am going to write that all the even rows are purls… but its the repeat rows that I need help with

the pattern looks something like this (there are a few starter rows and then the lace begins)

row 1: k, yo, lace pattern, k, lace, yo, k
row 3: k, yo, lace, k3, lace, yo, k

each time the lace repeat is increased by 1

so the row 1-4 you simply knit as is
row 5-8 you repeat the lace twice
row 9-12 you repeat the lace 3 times

so how would i write this?

would i write lace rep once (or twice or three times) each row?

or could I write 2(lace), 3(lace)? this one is more mathematical - make me think of my calculus days, but i don’t know if it would be translated with all knitters

or could I just write a note at the beginning of the pattern saying that an additional repeat is added every 4 rows?

row 1-4 you simply knit as is
row 5-8 you repeat the lace twice
row 9-12 you repeat the lace 3 times

That’s how you would write it, putting brackets around the part that’s repeated again -

Row 5: [k, yo, lace pattern , k, lace , yo, k] rpt twice
row 7: [k, yo, lace, k3, lace, yo, k] repeat twice

I would be more happy with a more intuitive variation.

Tell before: all even rows are purl.
The odd rows have a repeat as follows:

row 1 … lace repeat as stated below…
row 3

in the odd rows you repeat the lace part gets worked once in the original row, then with each following row it gets repeated one more time.
Best place markers at the beginning and end of the lace sections and repeat the lace section as many times as fit between those markers.

Is that doable for you?
