I guess it depends how often. Sometimes I do go close to the limit, but not often. I only occasionally do max statics, whether dry or in the pool.

I push myself a lot with CO2 and O2 tables and pool training, but hardly ever to the point of samba. If it does happen I try to do something different next time. I don't think it's good to get close to samba often.

It is true that extreme hyperventilation significantly lowers the limit - my static and dynamic PBs, both dry and in the pool, have all been done with less hyperventilation than I usually do.
