Windows system monitors can filter too, but it doesn't help. You either get flooded or miss important events (usually both).

Not so easy. You will discover that extra add.l will not do +2 cycles each. Some will do nothing and then suddenly you will have lots of cycles. This is due to chipmem timing alignment.
