Robert,
There's seems to be a (temporary?) problem with your website.
Thank you. I was doing some maintenance on my server for a short while through the night, and that made my sites unavailable during that time. All is back and running.

In Lightroom, I have around 130,000 files that are all from paid jobs over the last few years (wedding, portrait, commercial). There are no personal files or art and stock files (they would account for even more high ISO files).
These are the percentages from these files (pretty well exactly what I expected with the mid range 400 to 800 predominant)
100 ISO - 7.25%
200 ISO - 15.21%
400 ISO - 40.49%
800 ISO - 23.68%
1600 ISO - 11.92%
3200 ISO - 1.45%

if anyone likes fiddling with php and wants to make something of their own, here is the simple processing engine part of the script that I made - to give a head start:
if($_POST['calc']){
$iso = $_POST['iso'];
$isottl = array_sum($iso);
$cnt = 0;
foreach ($iso as $val) {
if($val>0){
$calc = round(($val*100)/$isottl, 2);
$per[$cnt] = "$calc%";
}else{
$per[$cnt] = "0%";
}
$cnt++;
}
$perttl = array_sum($per);
}
with "name=iso[]" being the form input Post value, and "$per[]" being the returned array containing percentage values
