As a little example, I did run it against my current network-admin code (it took me about a month and a week to rewrite it), here’s the result:
Totals grouped by language (dominant language first): ansic: 4443 (100.00%)
Total Physical Source Lines of Code (SLOC) = 4,443 Development Effort Estimate, Person-Years (Person-Months) = 0.96 (11.49) (Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05)) Schedule Estimate, Years (Months) = 0.53 (6.32) (Basic COCOMO model, Months = 2.5 * (person-months**0.38)) Estimated Average Number of Developers (Effort/Schedule) = 1.82 Total Estimated Cost to Develop = $ 129,331 (average salary = $56,286/year, overhead = 2.40).

So I’ve done my work in about 1/10th of the estimated time, and in my spare time! I don’t know whether this means that I’m really really smart, or whether Software Engineering estimates (or this program estimates) are non-functional stuff.
Anyway, I had a laught with this
