@Rafael, I don not think your idea is a vague concept at all. Being able to find the almost pertect amount of time to sleep it's something I can't yet figure it out, and yes amount of ideal sleep varies per individual and data about it - and the fact that there is no conclusive study as Petr mentions and adds that there is "a wide range" being able to lfind the your personal sweet spot becomes essential.
@Petr you say that is is not easy, perhaps not, but due that the app have lots of stats should help to determine this - I understand maybe some supposed ideal sleep ends being a "bad sleep" (overall, not counting if something disrupted your sleep that particular time) rating of that day coul be taken into account and maybe a Tag do add something like "Sleep disrupted or so" to calculate the ideal time. Taking rating into account for a specific amount of time could lead to calculate de ideal sleep (I guess taking at least a baseline of minimun amount to sleep of maybe 6hrs as the study suggests - as sometimes one can sleep just 5 hrs and feel great, but that is not healthyin the long term)
You also add "In stats we allow to make a regression analysis and you can determine your optimal sleep length to maximize deep sleep or your subjective rating of your sleep,"
Well, first, those stats are very hard to read, second having to calculate loooking at those stats could take a loooooooooong time - and this is something the app can calculate by itself (given the "advices" options that tells your based on this or that, you coul improve deep sleep from this hour, and all those advices - means the app DOES calculate by rating, lenght, even the hour you went to sleep as a factor on those advices saying "you should try to sleep at xx time" - so this IS possible (obviously I don't know if hard to implement, but due to your comment to look at the stats to find optimal sleep lenght, then why those stats can't be calculated instead of looking several amount of stats by oneself to get de idea? ) And of course, if this calculation can be made, the result should be to take into consideration not a FACT t will be super useful to have it as a guide. That is why stats are for isn't it? to calculate estimates based on different factors. In this case, Rating (I think) would be the most important one as sometimes deep sleep is not calculated correctly due to misplacement of phone, etc. But an estimated "ideal lenght" coud be made - as guideline… What Rafael adds later about research on sleep, I think it would be accurate eiither - as you already said, it widely varies and studies are not conclusives - also, it varies on individuals, age, etc.
Sorry for the long post! Now that I'm at it, I also agree with the first comment by @Guy about an option revolving around sleep cycles - on that issue, there are several studies indicating the benefits of it. (been using this cycle method for several months, and noticed how much it DOES impact on quaity - specially avoiding sleep inertia - fo that I have to use another app to calculate the time, and the set the alarm in Sleep as Android).
