love this feature. Look forward to the fix. I also thought points in common would be an interesting way to find similar charts.

You don't have to apologize so much, albummaster, bugs happen, and you do super well in fixing them. 😄 Thanks!

Apologies, on investigating further after seeing that the chart is still listed, I've found a bug where an artist in common is counted once for each album. I've just made a fix and & am re-calculating stats for the whole site (once this has finished, everything should be correct).

Apologies, there may be incorrect values currently cached for some charts. The similarity will get recalculated when a chart is next updated.

No, it's fixed now (won't happen again).

Apologies, I'll check into. I think it's something to do with a suspect album being removed from the other chart and the similarity not being recalculated. The list should refresh again in the next few hours, so I'll keep an eye and make sure it is changed.

EDIT: Seems correct now. Apologies for the issue.

The thing is, that's not the current similarities. I have 31 albums/34 artists in common with chart 4064...

I've just investigated this and it's to do with the way similarity is determined. Underneath, points are awarded for both albums and artists in common. Two points are awarded for an album in common, and one point is awarded for an artist in common:

For your chart, it looks like this:

Code:

ChartID Albums Artists Similarity
15207    66 67    199
14401    54 73    181
12322    49 69    167
4064    39 60    138
10543    43 50    136

Taking artists into account (as well as albums) helps to provide better matches.

Sorry if this has already been addressed, but the "similar charts" underneath my chart seems to always be inaccurate. For a good 3 months LosWochos' chart has been fourth on the list ahead of IrishMusichead's despite having 31 albums in common with LosWochos' chart and 42 with IrishMusichead's. When I press the magnifying glass next to my chart which shows a larger list, this doesn't differentiate, and several charts are placed incorrectly. In addition, charts like SilverWalrus' (42 albums) which have significantly higher common albums than other don't even appear on the list.

Why is it doing this?
