I worked a little of the NA RTTY QSO Party and messed up logging for the first couple QSOs. I have the callsign and exchange data, but can only guess at time and band.
My question is whether missing QSO entries in my log could penalize the other operators for those QSOs. If I submitted no log at all, they would not be penalized. I don't know of a way of logging a QSO, but leaving out certain data fields (like time).
