That's not the correct way to calculate effective wounds- If it was, the TX-225 would only have 12 (8/2+8) effective wounds, and that doesn't pass the sniff test, since clearly you need twice the number of wounds to get past the 50/50 save. Never tell me the Odds has a pretty in depth rundown (As well as some preliminary looks at how the Armor and cover keywords affect the estimate), but the short version is that effective wounds are (# of wounds) * (1/Probability a wound will occur). So an AT-ST has 11*(3/2) effective wounds (16.5), while Chewbacca has 9*(6/5) effective wounds (10.8), and the Emperor has 5*(3/1) effective wounds (15).
EDIT: @Matt3412 Beat me to it. The formula I gave you is just the inverse equation of what they described.
