It varies a lot really... we just had a bid for dec 4- Jan 28. the 4 most junior FOs on the inc side; 2 of them got an 8&6 staring Tuesday-Tuesday, one got a 7&7 Wednesday-Tuesday and one got a 5 on 3 off, 5 on 5 off line. So it’s pretty random... Captains tend to bid 4n3 go senior then 7&7 and 8 n 6 go junior. Generally all the 8n6 run Tuesday-tuesday, the 7&7 generally run Wednesday-Tuesday and the random lines are random some have all weekends off, some work every weekend in the bid period. Predominantly you will have 4 weekends off in a 56 day bid period regardless what line you get.... I hope my explanation isn’t too confusing
