For some reason my wife doesn’t believe that “oftener” is a real word.
Only I use when talk about the minorly baseball.
I’ve used the word on occasion and have heard others use it too, but not in the sense the OP has. Minorly is always followed by the word “inconvenienced.”
Majorly rad vibes from that riff duuude!! 
Minorly…Uh, I got nothing. Sorry. ?
