statistics from patchworks?

[Stephen Hemminger]

I did more research and found this paper:
  http://som.utdallas.edu/capri/contribution_pattern.pdf

Which had these metrics:

			Apache httpd	GCC	GDB	Mplayer	GAIM
Total number of patches 	2350	19487	7266	2652	1848
Percent of patch postings
 by core group			73.95%	80.12%	71.08%	24.66%	12.44%
Percent of patches submitted 
 or reviewed by core		88.72	90.85	91.91	75.76	71.81
Percent of patch submitted 
 by core with no reply		32.85	43.81	45.18	26.91	53.91
Percent of patch submitted 
 by non-core with no reply	43.3	46.06	27.98	32.18	32.22		
Average number of respondenents
 per patch			1.81	1.26	1.31	1.77	0.94
Average number of core group
 respond per patch		1.62	1.09	1.04	1.01	0.74
Average number of replies
 per patch			2.92	2.14	2.45	3.2	NA
Average numberof replies
 by core per patch		2.62	1.90	1.92	1.8	NA


My impression is that patchwork at least solves the no reply issue.
