you mean detailing as opposed to damp scrim/dry scrimming little top openers?
i detail all the way round the window after squeegeeing if it needs doing!sometimes some sides dont need detailing!so obviously i dont create extra work for myself!
i use blue flatweave microfibres most of the time by the way as i think they absorb at lot more and dont leave cloth fibres on the window!
i find though on a damp day dry scrim better for detailing as they last longer before they get too wet
