Cool, I look forward to the next version (17) and the one after that too (28). This is the first Fibonacci version number scheme I've seen, maybe in the spirit of how TeX keeps adding digits of pi.
The next version should be 5 + 6 + 7 = 18, not 17.
v(1) = 6
v(2) = 11
v(3) = v(1) + v(2) = 17
In general sequences, especially short ones, can have many ways to be generated, but I imagine this is the one the GP meant.
Wow, Winamp.
