There's not really such a thing as non-nutritive sucking during
breastfeeding, unless the feeding parent is not lactating. I prefer the
terms high flow and low flow sucking. The NS/NNS dichotomy is pacifer
vs. bottle feeding terminology. Sucking during breastfeeding is really a
continuum - the important thing to understand is the slower the sucking
(during the deep, rhythmic, effective sucking) the faster the milk flow,
and the faster the sucking, the slower the milk flow.
Jan Riordan once said in a lecture that during the colostrum phase,
sucking bursts of 10 or more sucks was reassuring in terms of the baby
sucking effectively. Infants with cardiorespiratory problems may have
shorter sucking bursts and still be transferring milk, but we're talking
healthy newborns.
We don't have huge amounts of research on the spatial organization of
sucking, but I agree that during the active phase of sucking, the
healthy baby feeding well uses a 1:1 or 2:1 suck:swallow ratio, things
differ as the first few large milk ejections are consumed. Every study
has to choose what to look at, and none cover all the variables. This is
why it's important to read widely and synthesize all the information.
There's certainly a lot we think we know that is going to turn out to
not be so, to paraphrase Mark Twain paraphrasing Josh Billings.

> It seems there's not strong evidence for the idea of 1 to 1 or 1 to 2 suck swallow ratio. Interesting. Would live opinions. The pattern of this two phase sucking that is described, seems to be describes sucking after onset of mature milk production. Am I wrong? Does this apply to newborns during colostrum production? It never really says.

> I really dislike the term NNS being used with the mothers and instead I say stimulating sucks and swallowing sucks. It seems to imply to them that the baby isn't getting milk. So many have become obsessed with milk transfer lately, to the point where they aren't able to relax and just enjoy breastfeeding.
