I have a mixed gauge result: 20/4 in double moss (gauge listed on pattern), but 25/4 in cable pattern (gauge listed for cable pattern in swatching portion of workshop). I’m worried if I go down to a US 4 to get my double moss gauge I will be too tight in the majority of the body, which is in cable pattern. So, I’m hedging my bets and sticking with the US 5. I will probably have to adjust how many sts I pick up for sleeves, as the sleeve has more double moss than cables.
