As an "old timer" it is rather hard to understand what problem "gates" are trying to fix.

I know that the concept is to lessen the traffic found in big fleets with a conventional mark rounding. It seems that gates only create new complexities that are worse than any single mark rounding senario.

I hate gates but apparently those wiser than I think they are the way to go. Just add a few more ambiguities to the rules...good on you.
