Do golf cart chargers always charge to equalize voltage?

Interesting that the manual says the batteries should bubble at the end of the finish stage. If finish means the end of stage 3 ie float voltage then that's new to me. If instead it means during equalization then that is normal. And they do recommend equalization every 30 days. It's not clear to me as the chart shows both float and equalization. They also state to avoid contiuous float if charged for more than once a week.
