Apologies for the confusion. I have amended the wording.
Miller appears to have done approximately 1hr 23min during the initial lap to the point of pictures being taken Gray Hewitt appears to be doing 1hr 16min during the initial lap to the point of pictures being taken Reno appears to be doing 1hr 11min during the initial lap to the point of pictures being taken These pictures may well have been taken before the end of lap 1. Looks like it was 2 minutes or so before the end of lap 1 going by Reno's data.
This actually makes things very marginally worse for Miller because, as everyone else is going faster, the time difference at the end of the actual lap would be greater than that noted.
Reno's Garmin Connect data would appear to show laps of
Lap One - 1:13.15
Lap Two - 2:27.55 (so a 1:14.40 lap)
Lap Three - 3:46.27 (This is a 1:18.32 lap that includes a slow, almost zero cadence straight - see below
* With that 1 minutes plus accounted for this lap is likely around 1:17 plus change)
(* There is straight section at the end of the ride, off of the looped part that accounts for a minute or so and is likely the run into transition that has been recorded by the watch)
