There is a lot on the WW forums which I read.

Read this blog, starting with this post then read all of them for the next 2 months or so:

I read a lot more but here are the main takeaways I got from it:
1. Your baseline is based upon gender, age, height, weight. It isn't based upon the 8 day assessment.
2. You do an 8 day assessment when you get AL which will then set challenge goals for you. Someone who was very sedentary before might get a challenge goal of 1 AP a day. Someone was already earning 6 APs a day might get a goal of 8 AP a day. However, if they were the same gender, age, weight and height, they would have the exact same baseline.
3.
You do not earn APs each day until you meet your baseline. The forums are full of people who say something like -- I did an hour of intense exercise and AL says I earned 0 APs so it is broken or doesn't work.
Basically these people don't understand the device. Let's say you get up in the morning and do an hour of intense exercise and you plug AL into the computer. It will say you have earned 0 APs for the day. Now, let's say you go out and have a day where you walk around a lot, climb some stairs and generally move around but don't do formal exercise. Chances are that at some point during the day you meet your baseline and then starting earning APs and by the end of the day you have earned some number of APs. On the other hand, let's say that after the work out you go home and sit in front of the computer for the rest of the day except for bathroom breaks. Chances are you earn 0 points because you never met your baseline.
4. One of the things being pointed out by many is that this device really does point out that -- for many people -- the "old" way of doing AP probably gives someone too many AP if that person is sedentary. In setting people's daily points, currently WW assumes that everyone is basically low activity which is a step above sedentary. So if you go out and do 30 minutes of low intensity or moderate exercise you earn a point or 2 of AP.
With the AL you might earn that point or 2 -- or you might not. If you actually aren't low activity the rest of your day and instead are sedentary then with the AL you will earn no AP as you didn't meet your baseline. WW right now
assumes you meet your baseline and so if you do any exercise at all you earn APs. ActiveLink doesn't assume anything. It actually checks to see if you meet the baseline and if you don't then you earn nothing.
FWIW, AL is definitely a better and more accurate way to do it. On some days I am sedentary and end up not walking around a lot. Currently I might go in and do the rowing machine for 45 minutes and I give myself a couple of APs. When I have AL, I probably won't get those points. And, truthfully, I probably shouldn't get them (I don't eat them so that is OK).
5. For most people APs earned using AL are lower than what people were recording. Members are notorious for over estimating activity intensity. AL tends to be more accurate.
6. Some activities have to be "named" on AL since the device doesn't read them well such as using an elliptical.
7. You can't use AL and record AP the old way. You use one system or the other. Once you get an AL the only way you can record activity is through the device. If you leave your AL home one day then you earn nothing and there is no way to record activity manually.
8. You have to plug it in to the computer (you can't use an iPad) to upload data and to see your progress. People generally aren't happy with the amount of info you get and feel fitbit gives better feedback.
9. It is cheaper than the fitbit
but you have to pay $5 a month forever to use it rather than only paying once for the fitbit. OTOH, the beauty of this is that it calculates APs for you. It is not as full featured as fitbit but there is a lower upfront and cost and you decide if the calculating APs for you is worthwhile.
10. If you open the package, it can't be returned and you can't sell it to anyone else. In other words, if you hate it, you can't transfer it to anyone else (fitbit doesn't have that limitation). Any customer services and product problems go through Phillips, not WW.
