Here's a simple example of how to setup a capture of the results of your load data. 

In this case we were to fortunate enough to have 3 different 9mm pistols. 2 are striker fired and one is hammer fired. Suggestion is that if you are going to share your loads with others, this will help you and them set appropriate expectations for their shooting experience. 

The green lines:

Every pistol will shoot a particular bullet (powder, bullet, primer) differently. Capturing your data, as seen below, you'll get to see which combination is the most consistent. Consistency in this case is defined by the smallest amount of difference between the highest and lowest velocity. For example, you may want to practice. You want your muscles and physical training to 'remember' the recoil, muzzle rise, and felt energy. The more consistent the experience, the 'easier' the acclimatization to this particular shooting experience. 

You may not want consistency in the round for your particular purpose. You may want the lowest speed possible for suppression. You may want the absolute greatest velocity safely possible for hunting or another purpose.
