Is it strange that Sligo-based R118 helicopter had been tasked at 9.40pm on Monday night to go 241km west and
R116 left Dublin at 11.02pm.
Wouldn't that mean R116 was then about two hours twenty behind R118, if you assume about an hour to get to the west coast doing about 100kts.
Not particularly. Tasking time would seem to me to be the time the coastguard picked up the phone and called the helicopter. Actual departure time of R118 could be anywhere from 10-30mins after that. Ill assume 30mins due to heavy refuelling and a departure of @ 2210
Actual departure time of R116 is known as @2300 after heavy refuel, so tasking time of say 30mins previous @2230.

The 40mins (approx) separation would (to me) be accounted for with trying to deal with the Irish military who couldn't provide top cover on the night.
