I don't know where you got this roasting strategy from, but it doesn't make any sense to me. I think you scorched your beans quite badly.
Coffee roasting is a Goldilocks process. Not too hot. Not too cool. You have to find the sweet spot.
I suggest you try the procedures described in this thread:Behmor - Optimizing 1/4 Pound Roasts
It's a tricky process, but consistently produces great roasts. From there, you can try variations to see if you can improve on it.
