I don’t think you understand my post and your example punctuates my presumption. Are you bummed that your car doesn’t fly…..or float? Context matters. Use case should dictate. Period.
Ten is completely arbitrary. A 30 Nosler at max pressure will be totally different than softly loaded 223. A fluted featherweight barrel will be different than a #5 or a Sendero or a ….start mixing and matching cartridges and contours. Again, context and use case.
In terms of correction factor, it’s only relatively to the number you’re trying to compare. And just like how 10 is arbitrary, 30 is also arbitrary. If you are unfamiliar with statistics, the correction factor may lead you down the wrong path. Context.
Now your just talking out the side of you mouth. A fully functional rifle should have a properly stress relieved barrel. Period. Hard stop. Anything else such as a hot barrel walking. is the rifle not functioning to its correct ability. Period. Hard stop. It up to the user if it matters that much to them if they want to use equipment that isnt performing as intended. But to say its ok due to its intended use is wrong. It was not designed that way and no rifle maker or barrel maker worth their salt will agree a hot walking barrel is correct and performing as designed.
To just quote Form that he posted after you that brian litz agrees with.
"highly predictive information of group size and MPI starts somewhere around ten rounds and keeps jumping up until somewhere around thirty rounds then leveling off after."
