Using 10 million when you are bootstrapping something that takes a long time is very computationally expensive when your estimate is calculated using an iterative method that takes even a few seconds to compute, 10 million X 3 seconds is I believe about a year as there are about 31.5 million seconds in a year :) So for my use case I am extremely appreciative of this methodology given the internal computation is a mixed model, so all in all a bit computationally expensive, and using this method is very nice to know about. Thanks for your blog Rick :)
