I don't get that chart...
What is the WISHED WEIGHT?
I put in her weight I assumed she'd be at adult size of 9.2 and that's what resulted.
Then I switched it to 6.8 and that was the second result...
How does that work??
For chosen the wished weight, I would see the common weight range of the breed. However, the date of birth & current weight are the critical data of this equation.
Let say, Chin Chin's date of birth is 03/20/2009, current weight is 3.409kg, the chosen wished weight are 4.5, 6.8 & 9.2; the result come out as 4.35, 4.37 & 4.44 respectively. The differences between 4.35 & 4.44 is only 0.09kg, so I dont really concern about that. Anyway, it is just an estimation.
