We've done this goals per 90 thing with him numerous times already.
That's his 4th season here, and he has played 3883 league minutes so far. If you want to know how small of a number this is, I could simply tell you that Solanke the one year wonder played 3333 minutes in his breakout year with Bournemouth. So even if Richarlison has had a terrific goals per 90 number over the course of his time here, it would make him nothing more than a different kind of a one year wonder: One whose minutes have been distributed over the course of multiple seasons.
Except there's another caveat to this, namely the massive purple patch he had in the 23/24 season:
That's 9 goals in 625 minutes, an extreme outlier of a stretch that could skew the numbers obtained from a sample that's already extremely small to begin with.
Including the purple patch : 3883 / 22 = 176 minutes / goal
Excluding the purple patch: 3258 / 13 = 250 minutes / goal

Believe it or not, his fragility is actually working in his favour here. Small samples are more open to getting skewed in quite [un]flaterring directions by statistical noise, and his numbers are benefitting from just that.
