Stop building 185.3 speed with Roberto
So I see a lot of people recommend this speed goal. While in theory this speed will allow Robin bird to action 5 time in the cycle 0, reality that only work if somehow Robin action at 0 av.
So here is the equation to calculate Robin speed (x):
x * (1 - AA) + BA * x / 1.8 =150 (for cycle 0)
x is Robin AV, you take 10000/x = Robin spd, AA is for any action advance you have at the start of battle, BA is how many bird action do you want
So let say you have Robin S1 without any extra, and want 4 bird
x * (1 - 50%) + 4 * x / 1.8 =150 => x ≈ 55.1 AV => Robin spd ≈ 181.5 - 19 (the LC) = 162.5 before combat
For 5 bird you would need close to 200 spd before combat just to reach it with her sig
Also if you using Amphoreus set then use this
x * (1 - AA) + BA * x / (1.8 * 1.06) =150 wrong because I'm stupid
x * (1 - AA) + BA * x / (1.8 + 0.001368 * x) =150
Correct me if I'm wrong on any of this
