Minimising Attack Stat Experience for Confusion

Minimising Attack Stat Experience for Minimum Confusion Damage
===============================================================

Using information from http://www.smogon.com/ingame/guides/rby_gsc_stats

Pokémon gain stat experience equal to the Pokémon's base stats defeated.

63002 stat experience gives the maximum 63 stat points.
25600 stat experience can be obtained by vitamins.

Therefore the stat experience that has to be done via battling is:

is 63002 - 25600 = 37402.

Our goal is to minimise the attack stat, while maximising the rest.

Chansey has the Highest HP, Special and Speed to Attack ratio
(250 HP| 5 Attack| 5 Defense | 50 Speed | 105 Special)
Magikarp has the Highest Defense  to Attack ratio
(20 HP | 10 Attack | 55 Defense | 80 Speed | 20 Special)

Step 1: a) Max HP -> b) Max Defense - > c) Max Special

   HP     Atk    Def    Speed  Special
a) 37402, 00750, 00750, 07500, 15750 (150 Chansey)
b) 37402, 07420, 37402, 37402, 29090 (+667 Magikarp)
c) 37402, 07820, 37402, 37402, 37402 (+80 Chansey)

Step 2: a) 230 Chansey -> b) Max Defense -> c) Max Special

   HP     Atk    Def    Speed  Special
a) 37402, 01150, 01150, 11500, 24150 (230 Chansey)
b) 37402, 07750, 37402, 37402, 37350 (660 Magikarp)
c) 37402, 07755, 37402, 37402, 37402 (+1 Chansey)

Step 3: a) 231 Chansey -> b) Max Defense -> c) Max Special

   HP     Atk    Def    Speed  Special
a) 37402, 01155, 01155, 11550, 24255 (231 Chansey)
b) 37402, 07755, 37402, 37402, 37402 (660 Magikarp)

So miminimum attack stat experience is 7,755
obtained by defeating 231 Chansey & 660 Magikarp

Stat Points = int((SQRT(7755-1)+1)/4)

= 22 (out of 63)
