Well for starters you can use Torres 1324 pr way back when he was no where close to his peak. And he ran smart during The outdoor season to maximize his potential for worlds. One would think from that he might go 1312-1316 if the pace is there.
Heres gouchers take on where he is
"After Nationals I came home and really focused on getting in 4 solid weeks of training. Mark and I felt that it was important for me to gain as much fitness as I could in that time. I'm in my 4th week now and these have been the best 4 weeks since my surgery. Kara and I head over to Europe on the 23rd (July). We will be running a 1500m in Greece on the 27th and then we will head up to Belgium where I will run the 5k going after the standard. If for some reason I don't get the standard there, I will go onto London or Berlin for another attempt."
