I think I can understand the purpose of the moderators not to allow the post about decision correct/not correct within 24 hours.
However if the regular posters keep answering within an hour, the attraction of the search is gone for the readers in other time zones.
I myself have also indulged myself in trying to be the fastest replier.
However for me this did not always gave the satisfaction.
Being ultra good with using the most effective search parameters has nothing to do with aviation.
I find myself letting go more and more challenges after finding the answer within half an hour.
I myself am more interested in the stories behind the airfields, aircraft, especially if someone has visited or flown it themselves.
I think this is often an neglected part of the challenges.
