I have no idea why you would do the 128 step thing with an even number of pokemon in your party. A better way is thisIf I am going after Regigigias and my desired frame is 187, there are 4 roaming pokes and 4 in my party, then I take 128 steps, so I subtract 9 from my initial frame giving me 178 and then I divide by 2 for journal flips giving me 89 journal flips correct?
187 (target) - 1 (Regigigas frame) - 4 (roamers)= 182/2= 91 journal flips. Just be standing in front of Regigigas so you can just press A.
