Can i juct check that this means

I work four rows decrease one either side on the fouth row, then work another 4 rows decrease again on the four row, then
work 6 rows decrease on the 6 th row, and do this four times/? is that right?

Decrease 1 st as before each end of next row, then on 2 foll 4th rows, and then on 4 foll 6th rows ending with a RS row.

You’d decrease at each end of the next row, then work 3 rows and decrease on the 4th; work 5 rows and decrease on the 6th 4 more times.
