This is incorrect.

OCW method recognizes that trying POI to POA is simply a matter of dialing on the scope. So the fact the group you identified in the thread I linked is close to POA is irrelevant - add 4 clicks to the scope turret and your theory is destroyed and the result of the analysis changes - because group 3 wouldn’t be “on target” any more, and other groups would be.

That’s not the correct methodology. If you follow OCW method correctly, it won’t ever matter where the scope is dialed or where the POI of any single group hits. It’s all about where groups fall relative to their neighbors. The POA is only an opportunity to ensure the groups are all appropriately relative for one another.

However, I describe in that thread how to analyze the groups according to OCW principles. What you are looking at is the relative position of each adjacent group. Note the yellow curve I overlaid on the edited photo - it’s exceptionally unstable from one group to the next around group #3. Whereas the line is nearly flat between groups #5 - #7.

What that means - considering the inherent variability of charge weights, neck tensions, bullet weights, and case capacities, and under changing environmental conditions, load 3 will fall apart at range, while load 6 will hit very close to the same POI.

OCW method does not care about group size, nor about independent group point of impact. The entire array is what matters.
