Mangosteen: calculating pulp to waste ratio

[fruitlovers]

10 mangosteen fruits of randomly picked fruits weighed 34.6 ounces (981 grams).
The 13 seeds from those 10 fruits weighed .3 ounce (8.5 grams).
The rinds from the 10 fruits was 16 ounces (454 grams).
By adding weight of seeds + rinds = 16.3 ounces (462 grams),
and subtracting that from total fruit's weight then get the weight of pulp: 34.6 - 16.2= 18.4 ounces (522 grams) of edible pulp.
So the weight of the pulp 18.4. ounces is 53% of total weight of the 10 fruits. Waste (seed + rind) is 47%. So it's lees than 1/2 waste and over 1/2 edible pulp.
I did same calculation for achachairu which has only 1/3  edible pulp and 2/3 waste.
