SPUG: CPAN code worth $500M

I'm not sure that these estimates are even vaguely correct. When I run
SLOCCount on my system I get:
Total Physical Source Lines of Code (SLOC) = 56,622
Development Effort Estimate, Person-Years (Person-Months) = 13.86 (166.28)
(Basic COCOMO model, Person-Months = 2.4 * (KSLOC**1.05))
Schedule Estimate, Years (Months) = 1.45 (17.45)
(Basic COCOMO model, Months = 2.5 * (person-months**0.38))
Estimated Average Number of Developers (Effort/Schedule) = 9.53
Total Estimated Cost to Develop = $ 1,871,872
This code was written in three years by myself (mostly), while I was
spending half my work time doing other things. Now, I freely admit that I'm
a genius, but... I don't think that there's any earthly way that I'm as
productive as nine average programmers (13.86 person-years/1.5 calendar
years = 9.12 times average productivity).
I think the model in this software is flawed.

Not too far off.... The actual "study"
