Regards the DCL, were unable to give the QNH with the electronic clearance so we still need to either hear it from you or give it to you if you don't mention it. ATIS letter is not really needed but stand number does help to confirm what we have on the strip, the stand info can be dubious sometimes, and helps pilots/tug drivers etc situational awareness on the ground. Even so the amount of time and RT the DCL saves is great!
