Something else - are you solving for face mounted or vertices mounted speakers?

Hi Fons,
Have you any images of how the irregularity is distributed? There's something about the
icosahedron that's niggling at my brain but I can't quite put my finger on it, so I thought an
image might help....

Hello all,
For most of the day and evening I've been trying to find the error
in some of the code I use to compute AMB decoders and which has been
updated and extended recently. It fails on one of the test cases.
If
- I compute a systematic 3rd order decoder for a regular icosahedron,
using the standard pseudo-inverse method,
- apply the per-order rE gain factors which AFAIK are 1.0, 0.862,
0.612, 0.305,
- then it should produce a uniform rE of 0.862.
But it doesn't. I get a uniform rE of around 0.8 only if the 3rd order
gain is decreased to something like 0.1 relative to the zero order one.
The same test for 2nd order on a regular dodecahedron works perfectly,
giving a uniform rE of 0.775. As does 3rd order horizontal on an octagon
with rE = 0.924.
I've gone through the code at least 10 times and can't find any error.
Is there something wrong with my assumption that this should work ?
TIA, Ciao,
