Trying to implement CFTHREAD...unsuccessfully :( - asynchronous

Question

I previously made the post cfhttp in cfloop limit? use cfthread regarding making multiple CFHTTP requests to which I implemented the solution of making a XMLHttpRequest in a JS function to call my CFHTTP request from another file.
I've amended this so that it runs on an intertval timer but I seem to have an issue in that I'm only allowed by the host to make 3 requests per second but although I may set the interval time to even every 7 seconds I still end up timing out because the CFHTTP requests seem to pend and often make the request at the same time (which means it's taking me through the threshold).
I've read Ben Nadel's posts on using CFTHREAD but am having absolutely no joy implementing them at all.
My basic process at the moment is:-
Index.cfm contains a JS function that uses a XMLHttpRequest that calls playerSearch.cfm
playerSearch.cfm makes the CFHTTP request.
playerSearch.cfm then loops round the response and I display the current item from the loop as well as submitting another CFHTTP request to make a bid on the current item in the loop if it meets any of my IF conditions.
Index.cfm then keeps making requests every X amount of seconds.
Is there a way I can set the CFHTTP request itself to make its request every X amount of seconds (maybe using the sleep function in CFTHREAD?) and how would I display anything inside a CFTHREAD as I don't seem to be able to?
Also if I were able to make the CFHTTP request itself make the request every X amount of seconds then would I be better just calling that directly and would it keep looping continuously?
Any feedback would be much appreciated!
EDIT:
Index.cfm
<script>
var searchTimer = null,
searchInterval = 1000,
startPosition = 0;
function startSearch() {
if (searchTimer !== null) return;
searchTimer = setInterval(function () {
startPosition = startPosition + 16;
var xhr = new XMLHttpRequest();
xhr.open("GET", "playerSearch.cfm?startPosition="+startPosition, true);
xhr.onload = function (e) {
if (xhr.readyState === 4) {
if (xhr.status === 200) {
document.getElementById("counter").innerHTML = xhr.response;
} else {
// Error handling
}
}
};
xhr.onerror = function (e) {
// Error handling
};
xhr.send(null);
}, searchInterval);
}
function stopSearch() {
clearInterval(searchTimer);
searchTimer = null
}
</script>
