How did the 3/5 compromise change at the end?

I think it changes for when the southern people get most of their delegates or maybe when there's most issues going on in the houses of representatives.

The population of slaves would be counted as three-fifths in total when apportioning Representatives, as well as Presidential electors and taxes. The Three-Fifths Compromise was proposed by James Wilson and Roger Sherman, who were both delegates for the Constitutional Convention of 1787.
