As I said in my reply to your Tree-Mail, you will need to monitor the speed of growth. If mowing at two weeks takes off more than 1/3 of the leaf blade length then two weeks is too long. If mowing every two weeks cuts off 1/3 or less of the leaf blade length then two weeks between mowing is fine. So it could be true but we can't tell without being there because it depends on how fast the grass is growing.
