Is it just me or does the estimate feature on the wish list not work very well? My wish list is totally full, yet only 7/200 books have an estimated date for the wish being fulfilled. Yeah, I have a few obscure stuff on there, but mostly not. Guess only the stuff that gets posted a lot has an estimated fulfillment assigned to it.

The estimate is based off of the frequency of posting so if it hasn't been posted in a while or much, it won't have an estimate. It can't really create an estimate if there is no data to calculate it from. The estimates aren't really that good anyway because just because 10 people posted a book last week doesn't mean anyone will post it this week or next.

The estimates are fun to look at but not very accurate because its just too much subjective data.  For example....2 weeks ago a copy of a WL book I have got 10 copies posted, so it gave my estimate as 1 week.  But now this week only 1 copy has been posted so it says it will be 10 weeks.  The estimate doesn't have a very long memory and is based only off of the last week of postings as far as I can tell.  So, fun to look at but don't make any bets on it lol.

In engineering we call extrapolations a "guess" or "forecast", only interpolations get called "estimates."

And yes, the book has to be highly requested before it consistently gets an estimate.  I have 3 books on my WL that actually move (I've dropped 60 places in one of them this past year), and none of these always list an estimate.  When a book has more than 1 posted in a week then I might get a temporary estimate and that is it.

I take most of the non FIFO-info on the Wish List with a grain of salt as anytime a member clicks on the "do not move it to my TBR shelf" (which I almost always do), then about half of that data is removed from the system.  There is a book I saw posted to the system before Christmas and already it reads as the last book posted being in 2009 (shrug!).

"anytime a member clicks on the "do not move it to my TBR shelf" (which I almost always do), then about half of that data is removed from the system"

Wow, I did not know that. I always click on do not move to my TBR Shelf because I use the "books on hold" list on my bookshelf for the same function. I didn't think I needed another list to monitor. I never realized that not moving the books over to a TBR list would mess with the data.

I never pay attention tot he WL estimates on here or SWAPADVD. I have DVDs over there that have had a 1 wk estimate for 2yrs now.  I would just buy them but at this point it's become kind of a "thing" in that I want to see how long it will take.

Wow! A one week estimate for two years! Hilarious. :)

Instead of trying to estimate with arcane algorithms, I wish PBS would just "state the facts" for both the wishlist and the bookshelf. Position in queue, how many of those are on hold, how many have moved in the last week / month / year / ever, for all formats of the title in question. I understand why not, it could discourage new members, but we're all educated adults and capable of interpreting the data as we see fit.

I used to (back when I had time on my hands) use the note feature to keep track of how fast I moved up the wish list queue. I'd write 23/27 on 1/5/2012, or whatever, and then update it every couple of months. It didn't take long to figure out which book wish lists moved and which didn't. I agree though, just the facts would be fine with me.

I would like to know where the idea comes from, because I do not believe it to be true. The information needed is all stored in the Transaction Archive, which no member can delete anything from. I don't know how or why the TBR action would affect anything. Was this something that someone actually heard through Feedback from the PBS Team, or just something said in the forums?

Thank you for describing how this function works.  I'm new and the N/A was confusing me.  Now I understand.  Thank you again for your discussion.

I pay no attention to the Estimate thing at all...it is virtually useless in my opinion.

I ignore it also, as most of my WL books have no estimate anyway.
