Mindmaps, general method to get regular/harmonious circle shape for level 3 and more
I have rewrite the grow function.
Now you have to specify nold, which is the number of leaf descendants.
That is, count the number of descendants who don't have any child.
Cat's Xshift and Yshift are kept.
But I renamed the internal overall xxxx as smuggle xxxx.
Because we are smuggling the parameter over the \pgftransformreset barrier.

UPDATED ANSWER to your edited question. Just define some counts for the various levels and introduce some offset angles. (More generally one will probably need to add some level-dependent additional angles, or do an automatized version, which the lowest code will get turned into at some point.) For your current example this seems to be sufficient.

OLDER ANSWER: This is some aux file hackery. The lowest code may be useful for writing an automatized version of the above code.
This code is not too serious an answer. So, yes, one can write stuff to the aux file and recover it when needed. But I definitely do not claim that this is a universally working code. Probably one has to choose the parameters differently. In order to have more than one mindmap, one needs to give the garlic growth a unique id (such as A or B). (I do not like onions, so I called this one garlic.) One has to compile this a few times.

Overall I think it may make more sense to marry the graph drawing algorithms to mind map. Some spring layout or whatever. Something where an algorithm tries to find the optimal values.
ADDENDUMM: This is work in progress. If I do not succeed, which is quite possible, here is a better structured and documented base version of the code. I have not added any explicit growth function, but this is the easier part (IMHO). It stores the number of leafs in the aux file and also computes a quantity m which is explained in the code.

{Let us define an array $m$ recursively as follows. For any \emph{outermost}
leaf
\[
m_{i_1i_2\cdots i_k}=\alpha_k\;,
\]
where $k$ is the level and $\alpha_k$ is the level--dependent ``standard
angle''. In the code,
\[
\alpha_k=\texttt{\textbackslash pgfkeysvalueof\{/tikz/mmap/angle $k$\}}\;,
\]
i.e.\ the $\alpha_k$ are stored in the keys \texttt{angle $k$} in the
\texttt{mmap} directory. If the leaf is \emph{not outermost}, $m$ is defined
as the sum of the $m$--values of the children,
\[
m_{i_1i_2\cdots i_k}=
\sum\limits_{j=1}^{n_\mathrm{children}}
\max \{m_{i_1i_2\cdots i_k-j},\alpha_k\}\;.
\]
};
\end{tikzpicture}
\end{document}
I think one needs to clarify how the tree should look like. Then one can conceivably use the stored leaf counts and m entries to draw it.
