I think Fred was asking you how you arrived at a figure of 15.24 for your MAD Index. Or as the maths teacher at school used to say "show your working" (innit?)  ;)

Hi Pete
That's ('a lot' - 2)² / a few = 15.625  not including the 1 new tune squeezed in today

... I recalculated and counting the 1 new tune today ... no significant change from 15.24 ;D

x^2/y = 15.625
x^2/(y+1) = 15.24

divide the two to get:
y+1/y = 15.625/15.24
15.625y = 15.24y+15.24
0.385y = 15.24

y = 40
x^2 = 625 => x = 25

So 27 boxes, 2 of them projects and 40 or 41 tunes.

and then there's the pipes, proper accordions and ...

Call the doctor. I need to learn a lot more tunes...or sell some boxes.

Been so busy working on other folks instruments that I sold out of my own restorations on the website. I hope to have 15 up before Christmas so check back soon and help me out.

Lies, damn lies, and statistics!

If you need to work the numbers to justify it, then you are MAD, but in denial.
If you don't need to work the numbers, then you already know you are MAD.

What do you do if the number of working boxes you have = the number of project boxes? It doesn't seem to matter how many tunes you know, the index works out to zero.
I think M includes both working and non-working boxes.

Of course! So that, if your boxes are all project boxes, then your index is zero.
And you aren't suffering from MAD at all.....and you can justify buying a playable box so you can learn a couple of tunes.

In fairness don't think that the term "Aquisition Disorder"  can really apply to stock in trade. Unless you go on to take drawings from the business in melodeons rather than cash.

That's ('a lot' - 2)² / a few = 15.625  not including the 1 new tune squeezed in today

... I recalculated and counting the 1 new tune today ... no significant change from 15.24 ;D
x^2/y = 15.625
x^2/(y+1) = 15.24

divide the two to get:
y+1/y = 15.625/15.24 :D
0.385y = 15.24

y = 40
x^2 = 625 => x = 25

So 27 boxes, 2 of them projects and 40 or 41 tunes.

Eshed - Thank you for reminding me how to solve simultaneous equations. Melodeons are so educational ;D

If there's one thing I'll take away from this thread, it's how few tunes people think they can play - I'm quite surprised by that.

However, I was not surprised by how many melodeons people have.

Having lived through large residence and indifference  and now with teeny house and total support I can say it does make a big difference... at least four more melodeons*

It's when they and their assorted cases are scattered around the floor that you know there might be a problem. But they are as nothing compared to the piles of books and folders of tunes !
After considerable contemplation, I reckon the ideal number of instruments is always one more than the number actually possessed...and recovering from M.A.D. is more like entering into a period of remission.

It's a lot easier to count melodeons than to count tunes. I really don't have a clue how many tunes I can play but I know exactly how many melodeons are in the house.

I wonder, among those who have a large number of instruments, how many are played regularly. Maybe we should have a TRUE index and an EFFECTIVE index.

Same here; my morris repertoire alone must be around the 60 mark, then there's the (at least) 100+ ceilidh band tunes, the tunes I play with a Celtic-based quartet and the fun stuff I play for the hell of it.....    Not that I claim to play all of them faultlessly (or even necessarily the same way twice running!), but it's quite a lot of tunes.

Having tried to come up with some kind of a measure of MAD and it's severity in individual cases and noting comments - especially those from Blake and Greg. I think an adjustment to the formula is needed....

(M - 0.5B)2/(P+1) = MAD Index

This modification  recognises Project Boxes as aquired melodeons and in some cases the actual aquisition disorder may relate to unplayable but otherwise interesting  instruments, but discounting them at 50% recognises that they are being processed rather than merely held hostage.

I realised that I had a severe dose of MAD when I was recognised I was aquiring boxes faster than I was learning new tunes.

As before a score of 1 or more puts you over the tipping point into self diagnosisr. It does occur to me that  anyscore below 0.5  but above zero means that you haven't got an addiction to melodeon aquisition. If your MAD Index is in the range 0.5- 0.99 you may be at risk...

Clearly you can;'t learn your first tune without a box to play on. .... So when you get yor hands on your first box and have yet to learn a tune,,,,, Your MAD Index = (1-0)2/0+1=1...You are instantly a borderline case. Learn a tune and your index falls to 0.5....after that things can go either way.

Adjustment should also be made in the tunes part of the equation for acquisition of tune books that have as yet yielded no tunes.
