Anyone else have an opinion on how much difference that fraction of a minute makes? I'd love to hear from someone who is at least in the Top 10k (thus ensuring they know what they are talking about).
I had a smartass answer ready about cooking an egg, but I've scrapped it and I'll just tell you that the prevailing wisdom is that there is very little difference between 48 minutes and 47 minutes, and I'd even go so far to say that anything 45 or above is probably fine. Personally, I don't make any special effort to get a guy minutes for training unless he needs 10 or more.
