Increasing help

I am working on a scarf pattern. It has a 10 row repeat pattern with M1 (after marker) in rows 1, 5 and 9. After doing the first 10 rows, the increase instructions are as follows:

Cont as established, inc 1 st after marker every following 4th row until work measures 30 inches, ending of a 10th row of pattern.

Do I continue with the 10 row pattern as indicated, with increases in rows 1, 5 and 9 - 3 stitch increase with every 10 rows?

Thank you for any help provided!

Welcome to KH!
Sounds like you now want to change to every 4th row. So with the last increase on row 9, work rows 10, 1, 2 without any increase and increase again on rows 3 and 7, then rows 1, 5 and 9. It may help to keep a list of the rows 1-10 and mark off each as you finish with the increase rows counted separately.
