I know a while back Jagex changed the way repeating floors are calculated but I can't find where it was or remember how it worked. I think they made it so that if say you had all abandoned floors but one done, no matter what abandoned floor you did it would check off the one you don't have done and you would get the full xp? Is this right?

If you do a floor, it will check off some floor of the same theme if possible. I think it checks the highest floor below what you did, unless you have none, in which case it checks off the lowest floor above what you did. You get xp for the lower of the two floors, so if you do f47 to check off f44 or f44 to check of f47 you'll get f44 exp.

I'll try to explain this the best i can.

 

Basically, they made this update so that it is much easier for players to do floors of the same theme together, even if one of them have already done the floor that the party leader chooses to do.

 

How it works:

 

You have your different themes: Frozen, abans, furnished, abans 2, occults, and warped.

 

Say a party of 3 players want to do an occult floor. The party leader only has the occult floor 45 open. But players 2 and 3 don't have that floor open. However, player 2 has occult floor 39 open, and player 3 has occult floor 47 open.

 

With this update, players can do one floor, and get the exp from another floor in the same theme(Higher floors will take priority over lower floors). That same floor they get the EXP from will be the floor that is ticked off.

 

Hope this helps you understand ^.^

about abandoned, I don't think doing Abnd 2 (fls 30-35) can count for doing abnd 1 (Fl 12-17)

Correct me if I'm wrong though.
