Can't always get the best word to describe things.

Thesaurus and searching for synonyms is hit and miss at best.

Here's one that could be called

Familiarity

but that's not working for me.

When you listen to a piece of music you hear more the more often you play it.
Often happens out of the blue.
Upgrades to kit not necessary. The brain decides to give you more.
Why is that ?
Familiarity is not quite the right word.

I use words to describe the recent upgrades that are, at best close enough.
Others may understand or not
Recently the system seems more
flowing
real
warm
smoother

We need better words, I do certainly
