Argh, peeking under the hood of the CDF I see that they do things that I wasn't expecting.  Now I bag that subVI and just calculate the CDF from first principles using the Incomplete Beta function, it is more fun this way anyway.

Almost perfect. In some cases, there are tiny differences but I wonder if they are due to the number of decimal places used here & there. Thanks a lot for your help
