What is my top 10% score?

Sounds like you have a pretty firm grasp on what it would look like, and what needs to be done.

In the abstract, sure.

But trythil's a much more experienced coder than I am.

I'm also a much lazier coder, and already have several projects that I need to start/work on/finish/maintain.

Shouldn't this require very little coding though. Since the score has to be calculated anyway if it has 7 or more ops? Just probally need a dbase field to store the information and just display it on a certain page.

I may be totally offbase here, but I thought the reason we couldn't see all the scores was because of the database and processing power required to calculate that many scores in semi-real-time for literally thousands of videos.

I could be wrong since in theory every video with 7+ opinions has this score somewhere in their database entry, but perhaps they don't and only a certain number are within a certain delta of a high score.

I guess Phade or Derobert would be the best person to answer this though.

Even if its just a delta, it still is calculated. It allready knows the number, you can just save it. I'm not saying calculate on demand. Just save it when it was calculated. The algorithm, doens't know what videos are close to making the top 10%. It just calulates all videos with 7+ ops and then ranks them and only displays and saves the top 10% of them. If your video have 7+ ops then the number is calculated for the video. So why not show it? In escence we are making better use of all those calculations instead of just throwing away that processing power used to calculate it in the first place.

Without knowing exacly how things are stored... there is a vast difference between calculating and saving a score for a video with 7+ ops, and say, comparing all videos on the org, ranking them, and then saving this other completely seperate list.

But I don't imagine it's that slow, especially if you kept an index for each ranked video so you could `insert' newly 7 op'ed videos into the right spot, and shift things whenever an op was made.

Like DW said, Phade or Derobert would probably know best.
