Sounds reasonable to me: With what I've written I don't think I've ever been in a situation like the one you describe, with an algorithm split over several classes. I feel like a major point of OOP is that I can package the data and the methods that operate on it, in a single encapsulated package.

Whenever I've written in C, I've just ended up passing a bunch of structs and function pointers around, basically ending up doing "C with classes" all over again..
