I'd say it's close enough, and i'm very appreciative that someone would go to all this trouble!!
I based a departure time from the dojo on the earlier stated time that JW texted AS about the house being on fire at 1:43pm. He must have found that info from someone at AIW calling the dojo looking for SS. Remember, we're only looking at a ten to 15 minute span when LE called AIW and AIW calling the dojo, so a departure at 1:45pm is reasonable.
Also, JayMac suggested the the travel time would be closer to 40 minutes. I66 is known to have a lot of rolling parking lots in both directions and I was fortunate only to experience two of them. The 40 minute trip is most likely possible in the middle of the night!
