The reason you got the answers you did was because you didn't present the question as hypothetical. All you said is "what am I running?". If in the first place you said something along the lines of "before I go to the track, what do you guys think I'll be able to run?" then you'd get the type of responses you're looking for.

So.

Your typical GSR with boltons is capable of running in the mid-high 14s.
