jQuery scrollTop

On a Desktop, how do I get this following jQuery animation to start sooner as you scroll down the page?  It works perfect on a laptop but it takes a while to activate on a desktop.  I don't understand a lot about jQuery and am trying to learn more, thanks.

It is the Circle animation under Total Solutions: http://0c8.88c.myftpupload (DOT) com/innovation/

<script>
 if($('body').hasClass('page-template-page-innovation-php')){ 
     var Wt = $(window).scrollTop();
     var ofT = $('.totalsol').offset().top - $(window).height() + $('.totalsol').outerHeight() /6.5 + 10;
     var autopage = ofT + $('.totalsol').outerHeight();

     if(Wt > ofT && Wt < autopage ){
           
        setTimeout(function(){
            $('.anmation-box').addClass('show_box');
            setTimeout(function(){
              $('.icon1').addClass('run_animatio');
              setTimeout(function(){
                $('.icon2').addClass('run_animatio');
                setTimeout(function(){
                  $('.icon3').addClass('run_animatio');
                  setTimeout(function(){
                    $('.icon4, .icon5, .icon6').addClass('run_animatio');
                    $('#spinning_circle').removeClass('shaking shakeme');
                      setTimeout(function(){
                        $('.soltion_text').addClass('run_animatio');
                          setTimeout(function(){
                            $('.logo_fade').addClass('run_animatio');
                            $('#spinning_circle').removeClass('shaking shakeme');
                          },3000);  
                      },700); 
                  },700);

                },700)
              },500)

            },500)

          },200);


         }
      }

});
