I think that it would be alot harder to regulate a tournament on the local level using the CPR system. It would be to hard to keep all the fishermen in the tourny honest without a ref. in every boat. Not to mention that it is not needed. With the products we have today to help keep fish alive in the livewell sometimes it's better to place a fish that has fought hard or hooked deep in the livewell with these products even if your going to release them. Rejuvenade, and Please Release Me from BPS just to name a couple.
The additive restores the slime coat of the bass, just incase you touched the fish, or it hit the boat carpet. The additive will also help with any sores the fish might have, and literally save fish that bled all over the deck from being stuck too deep. It will stop the blood flow.
Also in the heat of the summer when oxygen levels get low in the lake, putting a fish in the livewell and adding hydergine peroxide in the livewell put instant oxygen in the water and helps the fish not only calm down but relieves the stress of a hard fight. So, no I don't think CPR is the answer or solution. As soon as something as pointless as CPR is enforced one tournament trail it wouldn't be long before the animal rights nuts start tring to ban an tournament that didn't comply. Even though scientific data stats otherwise.

Just my two cents,
