Have a look at the best marks for the week, as USATF reckons them:
BEST MARKS WEEK ENDING JANUARY 28
MEN
1500 - 3:45.55 Bernard Lagat (Nike) - Glasgow, SCO 1/27
Mile - 3:55.18 Alan Webb (Nike) - Boston, MA 1/27
WOMEN
1500 - 4:20.39 Desiraye Osburn (New Balance) - Glasgow, SCO 1/27
Mile - 4:31.35 Shayne Culpepper (Nike) - Boston, MA 1/27
3000 - 8:33.25 Shalane Flanagan (Nike) - Boston, MA 1/27 American Record
Now surely they took splits in Webb's, Culpepper's and Flanagan's runs that were superior to those of Lagat and Osburn?
I mean, Flanagan's run is 2 times 4:16.625 for 1500m.
