Puck.js onAccel callback speed is slow

Sorry I forgot to attach my code for reference. Please find below.

var accelOn = false;
var batteryLevel = Puck.getBatteryPercentage();
  
NRF.nfcURL("Puck.js 9e03");

setWatch(function() {
  if (accelOn) {
    Puck.accelOff();
    accelOn = false;
    NRF.nfcRaw(new Uint8Array([193, 1, 0, 0, 0, 13, 85, 3, 80, 117, 99, 107, 46, 106, 115, 32, 57, 101, 48, 51]));
    batteryLevel = Puck.getBatteryPercentage();
  } else {
    Puck.accelOn(1660);
    accelOn = true;
  }
}, BTN, {edge:"rising", repeat:1, debounce:20});
