It is good to be prepared in case they do ask for more. I like that it sort of makes you to tape the things we take for granted; whether you use them for an application or not, it will be nice to have many years down the road.
The website says "over 1600 DYS" but it has been there for a while.
I am sure the amount of applications varies month to month. Of course not all people post here, but even here some months only a couple of posters say that they are applying, and others it can be more like 10. When we applied for ODD, there were 8 posters that shared as well. A couple were asked for further information (and those got in the later).
