I worked with both Lennie Wright and Don Fay as long ago as 1962 in a band at Poole Harbour Yacht Club - rather different stuff to what they did with Samurai and Web. Don Fay is now back in the UK after a spell in Australia and lives somewhere in the New Forest area so I am told.
The purpose of this posting is to enquire if anyone knows whether Lennie Wright is still alive. I understand that he lived in the Norwich area for many years and had a son, Louis Wright, who is apparently no mean vibes player. However, I have been unable to find any mention of Louis via the search engines and no one in Lennie's original stamping ground of Bournemouth seems to be able to confirm whether he is alive or dead. I'd love to know - just for old time's sake!

SPLIT ENZ "Split Enz" ratings distribution3.84 / 5
(1 ratings) I don't understand this new calculation algorhythm. How could it be that only one rating of 5 stars produces the average rating of 3.84 ?! ![]() |

M@x, the problem I have with a weighted system is that every few onths the list will drastically alter, which will lead to at least three forum threads on how the site as a whole has failed and how could you even think of putting yadda yadda yadda at No. 1 as if you yourself made the list. I'd like to think my hard work is rewarded with a little weighting, but I think more harm than good will come of it.

Can anyone EXPLAIN how the new ranking system works?
Just give me a formula, the link to wikipedia doesn't help much in explaining
why e.g. Los Aivas (nr. 37) isn't Number One...

If anybody cares to give eduur a reply, I would also appreciate it. Because I simply fail to see the (probably easy) method being used based on the Wikipedia article. An example:
We have 5 albums: Album A, average 4,38, 58 votes. Album B, average 4,11, 32 votes. Album C, average 4,42, 29 votes. Album D, average 3,82, 44 votes. Album E, average 4,58, 20 votes. The Wikipedia article seems to imply that I should multiply the average rating (the grade in the article) by the number of votes (the number of students) and then divide it by 183, which is the total number of votes. But this basically only ranks the albums by the number of votes, which is the opposite of what was supposed to happen. So... how's it calculated? |

Short explanation:
Suppose that the average number of ratings for an album in the archives is 10. Also suppose that the total average rating is 3.80: N=10 R=3.80 now we have an album which has only one rating of 5.0: n=1 r=5.00 The weighted average is: avg = (N*R + n*r) / (N+n) In this case: avg = (10*3.80 + 1*5) / (10+1) = 43/11 = 3.91 Let's look at another album which also only has one rating, but 1 star instead of 5: avg = (10*3.80 + 1*1) / (10+1) = 39/11 = 3.55 Now let's look at an album which has 20 five star ratings: avg = (10*3.80 + 20*5)/(10+20) = 138/30 = 4.60 Or an album which has 20 one star ratings: avg = (10*3.80 + 20*1)/(10+20) = 58/30 = 1.93 See? Albums with only one rating start at the total average an slowly work their way up or down the chart as the number of ratings increases. The more ratings an album has, the more it's computed average matches the "real" average ... the less ratings an album has, the closer the weighted average "sticks" to the total average. |

^ of course that does mean that no band will ever score a perfect "5" - but that's no bad thing |

What?

^ now here lies an interesting paradox... Without the weighting The Who's Quadrophenia would currently be sitting near top of the Top 100, which would bring about a flurry of hateboy 1-star ratings to drag it down.
With the new weighting system this will not happen until it has a sufficient number of 4 and 5 star ratings to get it into the Top 100, which will render the hateboy low ratings ineffectual for quite some time.
Which is highly commendable. But not exactly a level playing field for the exisiting albums that have already "suffered" under the old system.
(I'm not having a go at The Who - the same thing will happen to the next major inclusion and to the next major release buy one of the big-names)

Yeah, but weird things happen here and there with the rating system. Livecrime is in the upper reaches of the prog metal top 100 with only 16 ratings I believe

Because it has only 1 1-star rating against it's 13 5-star ratings - ie it desreves to be there - and also DVD's tend to attract reviews and ratings only from fans of the band. Edited by darqdean - July 23 2007 at 20:38 |

I don't think that there's any ranking algorithm that could automatically separate the abusive ratings from the honest ones. ![]() |

Which is one of the reasons why live albums and DVDs should not be listed unless the visitor explicitly wants them (clicks a button). |

Okay, thanks, that makes very much sense now. I do notice, however, that album without any ratings at all are given a higher score with this system than albums with comparably low ratings. Are these albums excluded from the system? That is, are they taken into account when calculating the average rating for all albums in the archives, or not? |

AFAIK the total average and number of ratings are calculated from the ratings database ... so of course the computed average of albums without ratings has no effect on the calculation. It also doesn't make any sense to calculate and display the average for these albums.
