Keeping a training log will help you to decide if you are making the gains you wish to or what things need more work. Just like you might write down your performance at the gym in order to track your gains, this is the same idea. Write down a date and time. Write down any environmental factors that could have an impact on the performance of your range session. For example, if you have any injuries that limit or slow mobility that you usually don't have. Write down the weather patterns especially if it might have an affect on your performance such as rain, colder than normal conditions, etc. If you have any broken equipment or are trying new equipment or even a new technique I would even annotate that. With the drill results written down, this will tell you your strengths and your weaknesses. It is not as much fun to work on the stuff we need to improve on, but that is what will make you a better shot and a better rounded shooter if you start improving upon those weaknesses. On the other side of that, don't just ignore the skills you are already proficient at, do carve a little time out of your range session to practice these skills to ensure that these skills are not getting rusty. It is even a good idea to track your dry fire results. Things such as draw time, split times, and depending on how you conduct an emergency reload. If you like to run the slide over the time or slingshot it in order to load the next round from your new magazine this would work well. If you prefer to use the slide stop, you won't get an accurate time for this drill since the snap caps will not lock the slide open on empty. If your shot timer or shot timer app will not register the dry fire shots, then you can set a par time to beat instead.
