There've been scientific studies debunking the previous work done on that.
Cases where we think we're in sync are due to probability. In a group of three women, there's a good chance you're period will overlap with at least one of them often enough. There's no evidence that this happens with any kind of consistency, it's coincidental. I've been "in sync" with other women before, and I know how easy it is to think it's more than just coincidence.
There are things, like stress, which can affect your cycles. If you're with a group of women who are all undergoing the same type of stress, then yes it's very possible all of your cycles could be affected in the same way.
And those studies which tried to talk about menstruation syncing, didn't find any correlation whatsoever with ovulation, which is what your hormones are really about and what would affect sex patterns. Several women saying "I'm on my period," "Oh, me too!" doesn't mean they've formed some kind of pheromone-induced special fertility link.
Notice that four women living in a room all being in sync is not the same thing as a couple of "oh me too" moments. Repeated across hundreds of barracks rooms it isn't easy to write off as just coincidence.
But, from me it is merely a second hand observation. I won't be carrying your disagreement back to the source though, as my first wife was, and still is, a bit of a hot head, and confronting her with studies that contradict her experience is never wise.
