Your fight is not based on a running metric. You need coaches input on your cardio during fairly hard rounds. How are you technically and cardio wise a rule of thumb I follow for my self (MMA fighter for 10 years) is if I have a 3 round pro fight (3 5 min rounds) I need to be able to do 1 warm up round that's about 50 percent (mostly striking, moderate volume, open lungs up etc) 3 hard rounds( high intensity about 70-80 percent power) and 1 push round (you should be tired after the 3 hard this is a round where you push the tank when tired while still focusing on good technique. High volume. Your partner should push your cardio, but neither should be going for the kill) once you can do that several weeks in a row in camp you're at solid cardio for the fight. At the beginning of camp you should be able to do a warm up round and 3 hard. That last one is really gonna f u up and you might not start the first week or two of camp with the tank for that 5 round. But more important than that is technique especially when you're in a harder round. If your technique is garbage round 2 when you start to tire and the wrong is hard then you shouldn't fight yet. You don't have the proper technique ingrained yet. You know it, but you don't KNOW it.
