It's a good time to take a hard look at when teams reached the Bayon Temple pitstop and when they will likely be released, all for the purpose of estimating which flights they might get to Bangkok and then on to Delhi. So here is my take on it starting with 0700 arrival on flight 3K595:
Time to Do Each Task Efficiently-
With Camerman and Soundman, Get Through Customs speedily   30 minutes
Taxi from Siem Reap Airport to Gas Pump task                               20 minutes
Gas Pump Task                                                                               10 minutes 
Be driven in back of truck to Siem Reap Dock                                 15 minutes
Be driven in motorboat to Kho Andeth                                            30 minutes
DETOUR at Kho Andeth                                                                   30 minutes
Same boat back to land near Angkor Wat                                      20 minutes
Tuk Tuk to Angkor Wat, inlcuding entry formalities                         15 minutes
Find the Echo Chamber                                                                   30 minutes 
Transportation to Bayon Temple and find pitstop                           15 minutes
Fudge Factor needed to balance underestimatesof tasks              60 minutes 
GRAND TOTAL                                                                                275 minutes, or 4 hours 35 minutes
That translates as follows:
Nick/Starr - ran a near-perfect leg and finished around 1135am
Toni/Dallas - ran a fine leg and finished around 1140am
Terence/Sarah - had bad luck with the boat and lost 15 minutes as a result; finished around 1155am before the half-hour speeding penalty
Ken/Tina - were near the front of the pack until Tina had trouble finding the Echo Chamber; finished maybe 1200pm
Kelly/Christy - were burned by from airport taxi driver not knowing the location; finished maybe 1205pm
Anthony/Dan - screwed up big time on not knowing how to operated the gas pump when no other team had trouble, but made up some time finding the Echo chamber; finished maybe 1215pm.
Decent flight alternatives are:
PG904 REP BKK 0950 1045 connecting to IC854 BKK DEL 1330 1615 
It looks like the alternate flight connection for any lagging teams(of which none are seriously so) is:
PG906 1250 1400 REP BKK connecting to TG315 1745 2045 BKK DEL
It looks like there is an extended pitstop of at least 24 hours. Since there are no flights between 850pm and 950am, it is logical to rule out either a 12 or 36 hour pitstop. So teams will be released late evening and have a long time to wait until Siem Reap Airport will be open for morning arrivals. It looks to me that all teams will be on the best flight combination above.
