While we often strive to have our Pokemon at their peak condition at level 100, there are certain styles of play that require us to go beneath that, such as the Video Game Championships and the Battle Tower. While you may think that level 50 is just half of level 100, many slight differences exist between the two.
[((11 BP × BOOSTa × [NATa × (BSTa + 0.5 IVa + 0.125 EVa + 5)]) ÷ (25 × BOOSTd [NATd × (BSTd + 0.5 IVd + 0.125 EVd + 5)]) × Mod1 + 2) × STAB × RESIST × R × CH × Mod2 ÷ 100]
Above is a modified version of both the HP Stat and Other Stat formula for easy use at level 50. Whenever you get to a pair of [], you must round down your current total to the nearest integer.
Where:
+0 / -0 = 1.0 +1 / -1 = 1.5 / 0.667 +2 / -2 = 2.0 / 0.5 +3 / -3 = 2.5 / 0.4 +4 / -4 = 3.0 / 0.333 +5 / -5 = 3.5 / 0.286 +6 / -6 = 4.0 / 0.25
Attacks at level 50 often deal a higher percentage (1 - 2% more) and have a wider range (6 - 7% wider) than the same attack with the same spread would yield at level 100. This is because the same EV spreads at Level 100 are only 48.5% - 49.5% greater than the spreads at level 50, giving them higher stats in the broad scheme of things.
HP = [BST + 0.5 IV + 0.125 EV + 60]
Stat = [(BST + 0.5 IV + 0.125 EV + 5) × NAT]
The above formulas are modified versions of the HP Stat and Other Stat formulas for easy use at level 50. Whenever you get to a pair of [], you must round down your current total to the nearest integer.
Where:
The important part to notice about this formula is
0.5 IV + 0.125 EV
This also means
[(IV + (EV ÷ 4)) ÷ 2]
As you can see, it is important for the sum of every IV and four EVs to be an even number, otherwise you are wasting EVs. This will change your EV spreads somewhat, especially if you are using Hidden Power. However, if you do not wish to place EVs into a stat that is being lowered by one in order to get a specific Hidden Power, then the stats will not even show the lowered IV. Without any EV investment, IVs are grouped into pairs that will provide the same stats. These pairs are 0/1, 2/3, 4/5, 6/7, 8/9, 10/11, 12/13, 14/15, 16/17, 18/19, 20/21, 22/23, 24/25, 26/27, 28/29, and 30/31.
Modest Kyogre Level 50 30/22/30/30/30/31 Proposed Spread: 4 HP / 252 SpA / 252 Spe
HP = [BST + 0.5 IV + 0.125 EV + 60] HP = [100 + 0.5 × 30 + 0.125 × 4 + 60] HP = [100 + 15 + 0.5 + 60] HP = [175.5] HP = 175
Special Attack = [(BST + 0.5 IV + 0.125 EV + 5) × NAT] Special Attack = [(150 + 0.5 × 30 + 0.125 × 252 + 5) × 1.1] Special Attack = [(150 + 15 + 31.5 + 5) × 1.1] Special Attack = [(201.5) × 1.1] Special Attack = [221.65] Special Attack = 221
Speed = [(BST + 0.5 IV + 0.125 EV + 5) × NAT] Speed = [(90 + 0.5 × 31 + 0.125 × 252 + 5) × 1.0] Speed = [(90 + 15.5 + 31.5 + 5) × 1.0] Speed = [(142) × 1.0] Speed = [142] Speed = 142
However, you are wasting good EVs in both HP and Special Attack, as shown below.
HP = [BST + 0.5 IV + 0.125 EV + 60] HP = [100 + 0.5 × 30 + 0.125 × 0 + 60] HP = [100 + 15 + 0 + 60] HP = [175] HP = 175
Special Attack = [(BST + 0.5 IV + 0.125 EV + 5) × NAT] Special Attack = [(150 + 0.5 × 30 + 0.125 × 248 + 5) × 1.1] Special Attack = [(150 + 15 + 31 + 5) × 1.1] Special Attack = [(201) × 1.1] Special Attack = [221.1] Special Attack = 221
Therefore, to remedy this situation, you simply place the 4 leftover EVs from Special Attack and place them into HP.
HP = [BST + 0.5 IV + 0.125 EV + 60] HP = [100 + 0.5 × 30 + 0.125 × 8 + 60] HP = [100 + 15 + 1 + 60] HP = [176] HP = 176
And now you have the optimum stat distribution for a speedy sweeper Kyogre: 176/116/110/221/160/142.
A Pokemon's difference in ratio between its level 50 stats and level 100 stats increases as its base stats get lower. A Pokemon with a base 230 stat and a boosting nature only has 50.48% of its total potential, whereas a Pokemon with a base 5 stat and a boosting nature has 52.10% of its total potential. Because of this, a Pokemon's stats seem more balanced at level 50 than they do at level 100. While this does not make too much of a difference overall, it can give frail Pokemon a slightly better chance of surviving attacks or give weaker Pokemon a chance to do a little more damage.
