Game Development: Castles in the Sand

[Boorynns]

So if I got 1100/560/340 as 1/2/3

I should have 123 because :

half of 1100 = 550 < 560 so 2 still there
and half of 560 = 280 < 340 so 3 still there,

or would I have 121 (as 550 is more than 340) ? I pref to ask since barra was believing it wasn't possible and I'm thinking of using porphyry so pref to us less possible of this.
