Hi Doru,

Thank you for your answer... It's too bad we don't have these figures... What do you say about creating a list of projects that could be used to create such a baseline. I don't really have a precise idea about the number of projects that we might need to compute this thing ... but I think starting such a list might be a good idea. And then based on that we can eventually try to get the results. 

In the Book: Object-oriented Metrics in Practice the authors used 45 java and 37 c++ systems to get these numbers ... so I think we have to find at least 30 projects maybe. 

I am not promising anything but maybe I will find some time over the next few weeks that I can dedicate to doing this.

What do you guys say?

Hi,

We do not have those thresholds for Smalltalk, yet. It would be interesting to get them, though. We only need someone to do it :)

Cheers,
Doru
