I think Wed, Sat and Sun are the days Carcassonne (can't spell that!!) operates, so the lower number of DUB services on those days make sense.
Surprise, surprise, Ryanair will increase frequency on LGW and probably give seats away quite cheaply. Schedule-wise it looks like more LGW and less DUB. Weekdays should look something like along the lines of
FR 9852 ORK 1310 LGW 1445
FR 9853 LGW 1505 ORK 1630
FR 9854 ORK 2005 LGW 2140
FR 9855 LGW 2220 ORK 2355
Im guessing it will be once daily evening service on a Saturday and an afternoon and evening service on a Sunday. Strangely Aer Lingus do not plan to fly evening weekend services.
FR 9842 ORK 0740 DUB 0830
FR 9843 DUB 0855 ORK 0945
FR 9844 ORK 1010 DUB 1100
FR 9845 DUB 1135 ORK 1225
FR 9846 ORK 1705 DUB 1755
FR 9847 DUB 1820 ORK 1910
Im not sure if RE would be able to take advantage of this in any way, FR seem to have most of the bases covered. Perhaps an 1830 departure from ORK with a 1950ish departure from DUB might be useful though.
