COSC question

I question the current COSC standards of -4/+6. If all the current SWISS non-COSC watches I have purchased (4) in the last year (Mido Oceanstar(+1s), Hamilton KFCA(-2s), DJR TV-Screen Chrono(-.5s) and a Jacques Lemans 7751(+4s)) are all within +/- 4 seconds a day (measured on both a watch timer and real-world), Shouldn't the COSC requirements be more stringent? How much does a manufacturer have to pay for the certification?
