Yes, it is. I'm nit-picking here. The patch you posted before also
works, even without the [change -1]. But even adding the [change -1]
doesn't address the issues I mentioned. On a fast ramp, it still misses
some values and it still suffers from jitter. It's only details I'm
talking about here, yes, but since you decided to remove the features
from my version, I hoped to be able to illustrate them with words.
