Looks very good to me.
The "noise" as opposed to a straight line is often inconsistency/un-evenness of the individual beats of the escapement. In my experience, this is due to cleanliness or lubrication (including over-lubrication) of the escapement. I'd still say it looks "ok". The other reason for the noise is if the watch pickup is not getting a strong enough signal.
But if you want to clean that trace up, I'd first ask: did you clean the escape wheel and pallets, are the pallet jewel holes clean, and are the pallet stones lightly lubricated?
Very interesting you should post this. I was thinking the same thing. Off camera I started with my shellac flakes which I prefer but I had the same problem. Soft but not melting - was quite frustrating. Changed over to the stick and it was perfect. I have a huge bag of flakes but I fear they are now useless. Fortunately its not an expensive product.
