I think this is very sensible. Does anyone care to defend the current situation ?

Sure I'll try. All players know about the "abrupt" changes in reward. Therefore there should not be a large unpredicted response from the market during this change. The existence of the change is already factored into the price so theoretically the market is just as likely to jump significantly on any other day. It is the unexpected that really freaks out the market. Further, more frequent changes are more difficult to manage.
