I don't see how is it degeneration. It's just a different encoding format... Towards the end it looked very much like how you would transcribe English speech as Hungarian. I could read it fluently around maybe 50-70% speed. Japanese does the same (for words they borrowed from English), so I could actually understand lots of things in Japan which were written using katakana, just after a month, without actively learning it. I might have spent 2 hours in total memorizing the katakana and hiragana symbols. Dutch also became substantially decodable for me just after a day or two and after learning a few trivial transformation rules between spelling and speech.
