Microlog Development $$$

I have often wondered how many hours I have spent on Microlog. It is countless hours of fun and sometimes frustration. But it is definitely worth it. I guess my wife beg to differ :) Anyway; there is a site called ohloh. This site collects data from the Internet about open source projects. It analyzes the code for a lot of things. For example it checks how well documented the code is. Another interesting metrics is the calculated development cost. Here is a list of the projects that I am involved in:

• Microlog - $ 435,348
• Microproperties - $ 2,955
• Microinstall - $ 12,018
• Voxtr - $ 29,963

Interesting reading. Please notice these figures are not only due to my work, but due to other peoples hard work as well. But is these values realistic or not? What do you think?
