Depending on how much you shoot you should have time to replace all of the cables and string and still be ready. There will be some stretch depending on the type of material used but you should be able to have everything settle down in about 100 shots or less. Then once everything is re-adjusted you should be good to go. If you are just replacing your cables and not your string you should still check your nock and peep placement after the cables are installed because theymay move. How much depends on how stretched out the cables were. Nothing that a simple adjustment can't fix (peep and nock) everything else should still be fine
