Would you consider half a dozen indentation levels to be too many?  I
frequently go that deep.

To be honest, I've never counted them.  So why should I suggest someone
else what's a "good" value.  Programmers certainly should have got (or
develop) a feeling about what's acceptable and what's too much in their
own playground (or in project contexts where many people cooperate).

But since you were asking I got curious;  I pick one recent "C" source
from one of my toy projects and get this distribution of the amount of
indents

    80 -    // empty lines
   169 0
   254 1
   172 2
   122 3
    46 4
    34 5
     7 6
     3 7

 This measurement is an interesting idea.
 Gathering some statistics from what I expect is typical source for
my own code, and ignoring: blank lines; lines that are flush left;
and "non-code" lines; I get
     level  percent  percentile
    =====  =======  ==========
        1     69.6        69.6
        2     27.0        96.5
        3      2.2        98.7
        4      0.9        99.6
        5      0.4       100.0
 giving an average indentation of 1.36 levels.  The numbers shown are
calculated by considering the amount of leading white space in each line,
and rounding up to an integral multiple of one indent level (which
is four columns).

I tried it on a non-C project and the results were:
Level  Count  Percentage
  1     11843   52%
  2      6659   29%
  3      3016   13%
  4      1016    4%
  5       366    2%
  6        79    0%
  7        15    0%
Total  22994  100%
Total project size was 29K lines. Comments are ignored. Level 0 lines are ignored.
All function bodies are indented one level anyway, so half the lines aren't indented at all relative to the baseline.
The highest indent is 7, but since tabs are 4 spaces, those lines only start 28 characters in from the left, in a 100-char window. That's 24 characters beyond the 'baseline'.
