Webform calculator (I need to delay the result) https://www.drupal.org/project/webform_calculator

Hello, is there a way to delay the calculation for performance purpose ?
The problem is that I have a TON of formulas being calculated every time I type inside the inputs, and this is making the whole thing very SLOW.

I need something like: "Wait 2 seconds after keyup and mouseup > show formula results"
Well, this is how I managed to delay the calculation results in
webform_calculator.js
line 12, 13, 14

setTimeout(function(){
  Drupal.webformCalculator.evaluateAllFormulas();
}, 3000);
