What you might not be accounting for here is whether the boat was a seasonal resident of that slip. This is particularly the case with fixed docks, where you need more lines to secure the vessel. Even more so if it's a tidal area.
I keep my boat in a fixed slip with a 3.5 ft tide swing. It requires 8 lines on the boat. I'll also note the marina can get rough.
We all tie the bitter end to the pilings and leave the loop end on the boat cleats. We leave the lines behind when we cast off. When we come back, the lines are the exact same length they were when we left.
Loop 8 loop-ends around 6 cleats and walk away.
I spend a good amount time making sure all the lines are setup right to be able ride through an entire cycle of high and low tides. I make sure we're not hitting the dock at high tide or hanging the boat from teh lines at low tide. Once that is done, they go essentially untouched all season.
I wouldn't want to have to re-tie and retune lines every time I came back to the dock.
