If we go by what Lolzy said, Esther was partially right: it serves as a buffer against Aptitude drops, since your stat is still hardcapped without it.

... kind of pointless, though, considering how many points it takes to equal a single scaled point, close to 80.

I'd test it, myself, but my only high levels with stats close to/ at the hardcap are corrupted, so low/no aptitude, there.
