Igor, let me help you with some practical knowledge on pips and high level players.
One of my players use this rubber before.
From brand new to worn out, is only around 30~45 days…. Same style of play…
She likes the pips the best around 2nd week, and around 4th week, the pips will start breaking.
Of course we talking high level player, with 40+ hours of hitting a week.
So 160 hours to kill a pip is a bit fast, but not unnormal.
if we take 45 days, it is more around 200 hours.
She hasn’t found a pip that can last 2 months yet.
Maybe for you, old = 160 hours of play? if you play 2 hours a week, that is 80 weeks, so 1.5 years old for you?
But for her, it is only 30~40 days old and I’m sure no different to Manika.
So unless you spoken to Manika, please stop making assumptions or fake news.
