Good news, everyone: I was misinformed. We sample the crank angle at 100Hz regardless of refresh rate, but we are smoothing the value in firmware before reporting it (we compute a moving average of the most recent n samples). Without the smoothing, the signal is too noisy at the precision we need, especially for small angle changes. But we may be able to solve this by reducing the smoothing when cranking faster. Will report back when I know more. Sorry for the misdirect!
