There have been discussions about trips hitting in PA. Also I know some people say there are "triggers", so I decided to see what they are. I looked at PA MIDDAY triples and looked to see what numbers hit in MIDDAY for the 3 days preceding. Here are the results:
Priority : 4
073(307,370,730) 426(462,462,642)
Priority : 3
011(110,110) 072(207,702) 819(891,981)
Priority : 2
024(240) 159(159) 143(413) 245(245) 243(342) 026(602) 263(326) 323(332) 152(512) 069(690) 250(502) 394(439) 438(438) 087(807) 459(495) 494(494) 196(916) 538(853) 529(952) 589(958) 728(872) 669(966) 837(837)

002 004 023 047 049 057 059 071 080 097 104 137 148 151 181 197 217 222 226 232 289 299 330 353 356 372 435 441 474 497 523 527 531 547 548 568 605 613 616 618 673 675 707 722 724 748 760 767 774 789 840 852 857 860 885 889 900 956 959 968
I don't know what to do with it, but there you have it for MIDDAY to MIDDAY. Hope it helps.
