I haven't read Save Our Sleep but in first 5 mths of DD's life I did lots of reading on the net regarding getting her to sleep better, as well as positive stories of how SOS helped. If bub catnapped or if she woke up 1 sleep cycle after bedtime I'd get all in a fluster about what I did wrong, how do I resettle, etc. I tried patting her/patting the mattress/ shushing/singing/cry in arms - all of those methods drive me batty. In hindsight I wish I had just chilled out about it.
Against all the books we have a late bedtime - she goes to sleep when we do and that helps me get the most sleep as I sleep when she does. I've sidecarred the cot so when she wakes up at night it's easy to deal with her - I'd certainly lose my marbles having to go to another room. Mostly she wakes once or twice, occasionally she sleeps through. It is completely unpredictable whether she'll have a good sleep or a cranky catnap. Of course I don't have a toddler to deal with as well and can sleep in, so that perspective may not be helpful to SAgirl. I think trying not to stress about DD's sleep has made my life better.
(I say as I write this as she's fed to sleep for her nap next to me - perfect time for Bubhub).
