While I'm no expert on sleep studies, anecdotal "evidence" that I have heard regarding such subjects leads me to believe that humans are very adaptable critters. We can probably adjust to just about any length of sleep to wake cycle, provided it is regular, and that it involves some amount of REM sleep. 

In general, I've heard that long cycles are less efficient than short ones. The "DaVinci" sleep cycle (aka Polyphasic sleep ) of 4 hours wakefulness to 15 minutes of sleep is one of the most efficient in terms of ratio between waking/sleeping states. Thomas Edison is reputed to have slept this way. 

Longer periods, such as the 18 hour/6hour ratio that is common for most adult Americans involves a greater percentage of time asleep. (3:1) 

I've also heard of those on 24-hour sleep cycles, which involves staying up for 24 hours, then sleeping for 24 hours. This means spending half your time sleeping, rather than 1/3 of the time (as in a standard sleep cycle) or in an 16:1 ratio as in a Polyphasic sleep pattern. 

I would imagine a Dragaeran on a 20:10 ratio would get about the same amount of sleep over the course of a week, month, and year as an Earthling. It's possible that the ratio is slightly higher, however, due to the extra 2 hours of wakefulness in each day leading to a slightly less efficient sleep pattern. 

Or perhaps it's normal for Dragaerans (and Easterners) to sleep two or more times in a day. (Though there does not seem to be any text evidence I can recall that would support such a theory).
