Better Pedometer - HELP NEEDED!

Looks like the filter is much smaller AND massively improved - no ringing that I can see.
I copied the filter taps from the code - so I could investigate the filter in javascript.
Hopefully not mis-copied.

// (3) Low Pass filter 
var filter_taps = new Int8Array([5, 6, -4, -17, -15, 4, 11, -10, -27, 8, 80, 118, 80, 8, -27, -10, 11, 4, -15, -17, -4, 6, 5]);

Here is the ringing on the V2.09.90 filter in response to a single arm sideways open and close.
