I love this concept and want to try it but IMO there is a variable it doesn’t account for.
In short, these technologies look for a flat spot in velocity which is perfectly logical.
Where I have a problem is that I know that no matter the components or methods there can be big swings in ES/SD.
Case in point: I need to start from scratch on an APR heavy target gun in 260AI.
Lupus brass is fire formed, necks turned, Redding bushing dies used with .002 tension.
Etc etc
The variable is ES.
I always record velocity while working up loads and even with equal components and prep things start with a big ES and then gets smaller and then opens again.
So who says the flat spot you see with 10 shot or a ladder is good info or just where you had two big ES numbers accidentally get close to each other?
