On the other hand I feel like estimating expectation value based on multiple hands with different outs is too tricky to be able to do on the fly.. even with rough estimation. I mean even taking the simple example given you have to be fairly sure that hes drawing out, he's not going to call something that give incorrect odds for both draws, and hes going to call incorrect odds for the 4:1. How often are you going to know villain well enough to make such estimations?
Estimating expected value based on on multiple hands with different outs is very tricky and not usually something you should be trying to do to any exact degree in the heat of a session. Ranges will be more complicated than this because you wont know villain well enough to reduce his range to only two types of hand usually. The best thing to take from this little section of the book you're reffering to, is to practice working out different odds that draws will have vs you and how much you need to bet to deny these odds. This will give you a feel for how to play vs those sorts of hands, and how to tailor bet sizing in general on very drawy boards like the one in Sklansky's example; where your opponents range is comprised of draws for the most part.

Remember though, often draws will be a much smaller chunk of someone's range so keep this in mind and also analyse spots where you are extracting mainly from weaker made hands to get a feel for this too. Everything depends on your opponents tendencies and it will be very rare to find situations where you can just say "ok he either has this draw or that draw and nothing else." but these examples are there to help you practice how to do your analysis in these spots and gain a better feel for playing against differently weighted ranges. The author isn't suggesting you should commonly be able to stick your opponent on this narrow and simple of a range to play against.
