I will try and be as fair to each side when I describe what the data entails
The key cycle data showing the abrupt reverse events (1162-2) shows the odometer reading and the time into the key cycle that the event occurred. Since another event occurred in the same key cycle (1162-1, the 3 point turn) it also shows the time between the 3 point turn and the abrupt reversal.
The CW used the GPS data from JO's phone and the data from the Waze app to try and line up where he was at the time of the first trigger event. They were able to deduce that JO (and the Lexus) were making a 3point turn on a specific road, ~ 11 minutes after the cycle started.
The issue with 1162-2 is that the Waze app has been turned off since 12:24am, JO's phone location is independent of the Lexus (and this has to be true for the CW as well as the defense) and all the witness testimony about the car's location, JO's location, etc. is a whole mess.
At best, the data shows that 1162-2 occurred on the same mileage as 1162-1, so it has to be within a mile range of the 3 point turn. It also happened ~ 8 minutes after the 3 point turn. So we can say that KR wasn't in Boston when 1162-2 happened (just an example) but we cannot say she was in front of 34 Fairview.
IMO, the data point that she connects to wifi at 12:36am makes it more likely 1162-2 was not in front of 34 Fairview. Rather that she missed the turn onto Beaumont and went down Beatty street instead. This scenario fits perfectly with the information that we do have: it's .7 miles away from the 3 point turn, its about 2 minutes from 34 Fairview which would align with her return to 1 Meadows Ave at 12:36am AND align with HB's statement that JO exited the car at 12:30am - though that was never brought up in testimony. We also know that KR missed a turn just 8 minutes prior so it’s reasonable she missed one on the way home too. Especially with how confusing that intersection/turn looks
12:30am - JO exits/KR leaves
12:32am - KR misses turn and reverses
12:36am - KR in vicinity of 1 Meadows Ave to connect to wifi
