Camera tracking a non-player object

I have to fighters in a ring. Both are AIPlayers.

I'm using the track camera resource in order to have a 3rd person camera - which is working fine. I can easily track either fighter.

However, what I really need is for the camera to be pointed directly in-between the two fighters.

Here was my attempted solution and the ensuing problem...

I created a torque logo object (a placeholder just so I had something I could see) called "ctarget" and made that the camera's target. I then change the position of the logo to be the average of the two fighters' positions.

Then I call the following function that calls itself to update - i assume - every 2 milliseconds...

// ========================================================================
//  camTarget.cs
//
//  This module contains a function for moving the the camera's target
// ========================================================================


function camTarget(){

   schedule(2, 0, camTarget);
   if ($prevmode==1 ||$prevmode==2){
      ctarget.setPosition("25.5293 -415.609 0.59669");
      ctarget.setScale(ctarget.getScale());
   }
   if ($prevmode==0){
      
    %xfrm = ctarget.getTransform();
   %lx = getword(%xfrm,0); // first, get the current transform values
   %ly = getword(%xfrm,1);
   %lz = getword(%xfrm,2);
   %rx = getword(%xfrm,3);
   %ry = getword(%xfrm,4);
   %rz = getword(%xfrm,5);
   %rd = getword(%xfrm,6);

   %w1 = $wlist[0].id.getTransform(); // $wlist[0].id is fighter number 1

   %w1x = getword(%w1,0); 
   %w1y = getword(%w1,1);
   %w1z = getword(%w1,2);
   
   %w2 = $wlist[0].pfocus.getTransform(); // $wlist[1].id is fighter number 2

   %w2x = getword(%w2,0); 
   %w2y = getword(%w2,1);
   %w2z = getword(%w1,2);
   
 %lx = (%w1x + %w2x)/2;
 %ly = (%w1y + %w2y)/2;
 %lz = ((%w1z + %w2z)/2) - 2;
 
 
   ctarget.setTransform(%lx SPC %ly SPC %lz SPC %rx SPC %ry SPC %rz SPC %rd);
   ctarget.setScale(ctarget.getScale());

   //the camera is set with...
   //$mycam.setTrackObject(ctarget);
   }
   
}

The problem is that it's incredibly choppy. The position of the object is definitely lagging to the point of the camera jumping and it's incredibly choppy. When I track a fighterwhile calling the setMoveDestination function, it's incredibly smooth.

My question is, is there a better way to do this? should I use something other than the scheduling of the camTarget function that would make it as smooth as the aiPlayer?

FYI - I also attempted to add the setDestination method to the staticshape c and h files, but my C++ chops weren't up to the task. But I figured that way, at least I could call the setMoveDestination with the average mid-point of the 2 fighters instead of directly making it equal to it.
