In the Miss Kingdom Contest, 1000 judges will judge each contestant on Elegance (k), Proportions (p) and Glamour (i). For Elegance and Glamour, higher is better, while for Proportions 100% is considered ideal. For calculation purposes this means 101% Proportions will be treated as 99%, 102% as 98%, etc.

Proportions are calculated by 209 - Height + Weight, and then rounding up to the nearest integer.

So 148.3 Height and 32.6 Weight gives proportions of 209 - 148.3 + 32.6 = 60.7 + 32.6 = 93.3 = 94%.

To get 100% Proportions, your daughter needs to have a Weight between 109.0 and 109.9 lower than her Height. So for 148.3 Height, Weight between 38.4 and 39.3 is ideal.

Judges will give their votes from left to right, then top to bottom. If you buy votes the amount of votes bought will be taken away from the initial amount of votes available for the other contestants, and your daughter's amount of votes will be calculated last (remaining votes).

Votes are determined as follows:

For each contestant, take the amount of votes still to be given out (starts at 1000), then subtract the sum of the judged property of all contestants who don't have votes yet. Divide this by the amount of contestants who don't have votes yet, and finally add the property of the contestant being judged. The result is rounded up to the nearest integer.

Example:

3 contestants don't have votes yet on Elegance, and there's 300 votes left. The first contestant has 55 Elegance, the second one has 125 and the third one has 80.

The first contestant will get (300 - (55 + 125 + 80)) / 3 + 55 = (300 - 260) / 3 + 55 = 40 / 3 + 55 = 13.33 + 55 = 68.33 = 69 votes.
The second contestant will get ((300 - 69) - (125 + 80)) / 2 + 125 = (231 - 205) / 2 + 125 = 26 / 2 + 125 = 13 + 125 = 138 votes.
The final contestant will get 300 - 69 - 138 = 93 votes.

Now if the first contestant is your daughter, and you buy 50 votes, the calculation changes as follows:

The second contestant will get ((300 - 50) - (55 + 125 + 80)) / 3 + 125 = (250 - 260) / 3 + 125 = -10 / 3 + 125 = -3.33 + 125 = 121.66 = 122 votes.
The third contestant will get ((300 - 50 - 122) - (55 + 80)) / 2 + 80 = (128 - 135) / 2 + 80 = -7 / 2 + 80 = -3.5 + 80 = 76.5 = 77 votes.
And your daughter will get 300 - 122 - 77 = 101 votes.

So buying 50 votes resulted in a reduction of 16 for both nr 2 and 3, for a total gain of 32 for your daughter.

Note that the Autumn vacation is only possible in September.
