Your numbers are skewed because many bugs were closed as a part or retriage at the end of the year. I personally closed more than 100 bugs in November. I do not think that 10 is sober since we need to take more engineers off coding to find the duplicates and already fixed. I think median is a better number to use since a few engineers are throwing off the curve. If they are not on maintenance the velocity will fall. Good news for you though, the 3 of the top five are on maintenance to start this off. > We have 59 time outs currently.

I can close an oops in less than a day, but I think I can fix only 2 timeouts per week. The oopses the Registry team have worked on last year were not invalid, I do not expect to close invalid oopses. We were able to fix a few timeouts by finding a common root cause. I think 2 our of 7 timeouts have common roots. -- __Curtis C. Hovey_________ http://launchpad.net/
