This doesn't prove anything. sa-learn --dump magic shows you what's inside. Also, Bayes is not a checksum system like Razor, that's its strength. If you learn something to it that means that it extracts tokens (short pieces) from the message and adjusts its internal probability for them being ham or spam by a certain factor. Or if it doesn't know that token yet it adds it. That the size doesn't grow can have several reasons, f.i. expiry or the fact that the db format seems to have some "air" in it, so that it grows in jumps and not continually.
