You should move var start below the definition of toggle. Now you'll be closer to the real number. Final step is to actually measure the toggle with an oscilloscope :)

You are correct. I should move start. It will be put on the work bench and tested when time permits. So far I have only been able to pay with the pico on my phone using OTG cable and briefly from my laptop last night.

I will update here if there is a significant change from moving the start.

Update:
Moving var start brought it up to 38.7 Khz.
```
function toggle(){
  "compiled";
  var A = digitalWrite;
  var B = B2;
  for (var i=0;i<10000;i++){
    A(B,1);
    A(B,0);
  }
}
var start = new Date();
toggle();
var end = new Date();
var time = end-start;
time = (10000/time);
console.log(time.toFixed(2)+" Khz");
```
Update:
33.28Khz
