I disagree. His listed 2:21 marathon PR would put him the top 40% of the starting grid of international elite division of the 2012 Boston Marathon. His 3:58 mile PR is nothing to laugh at - converting that time to the 1500, it just a few seconds off the "A" standard.
http://running.competitor.com/2012/04/news/boston-marathon-elite-fields-released_50598C'mon, he's not doing BBs like the cyclists are doing on GT rest days for an instant boost/recovery. Though he doesn't give the dosage he was using (just his weekly schedule), I'm guessing that with the ~18% boost in Hct he said he experienced, it's probably close to the dose & duration used in Durussel et al (~17% increase), where the test subjects after 4 weeks usage experienced a ~6% improvement in time ran on an indoor 3k TT (it sounds like he maintained his rocket fuel-induced crit for a couple of years).
I used the following site. His listed PRs for the 5 & 10 are several seconds faster than on the site you've provided. His half is about the same. The 2:21 marathon is also listed. He has a 3:50 road mile PR listed (Austin), but that would have to be on fast descending course?
