Usually odd rows are RS and even the WS, but not always, some may also have a ‘set up’ row for the pattern which will be the RS, then row 1 would be the WS. What’s the pattern? If you have a link to it or a picture that can help.
Yes, it does look as though the odd rows are WS, even are RS. Following the numbers helps - RS rows begin at the right edge of the chart and all the even numbers are there. WS rows begin at the left edge and that’s where the odd numbers are.
