I rapidly came up with a large number of drills. I wrote down 75 or so, but had ideas for many more. Inventing drills isn't particularly hard (though inventing drills that are useful long term can be challenging). It became apparent that I needed to pare the drills down to 52 drills in some sensible fashion. So, here's what I did.

1.0 is a deck that focuses on basic practical shooting skills. The drills in this deck involve a minimal amount of equipment, relatively short distances, and relatively easy target presentations. This set of properties makes it a sort of "every man" practice tool - its usable in dry fire as well as live fire, the full set of drills can be used on almost any range, and basically every shooter can benefit from the drills as they are written on the cards. The drills can be scaled easily, too, to make them harder as required (more on scaling below). And, its usable for any of the practical shooting sports - USPSA, IPSC, IDPA, pistol for various multi-gun and 3-gun events, etc.

And, I pulled in several drills and target arrays I've found useful from other sources - folks like Max Michel, Jr., Brian Enos, and Eric Stanley.

Hit factor scoring is complex for this kind of thing. Max Michel described a "time plus" scoring system for a few of his drills to me, that I adapted slightly to the scoring system that appears in the deck for use by USPSA or IPSC competitors. It effectively makes each drill a fixed 5 hit factor stage, placing emphasis on shooting good points, but rewarding speed a bit more than IDPA's fixed 2 hit factor scoring. IDPA competitors should use IDPA scoring values to practice appropriately for their game. Other games can pick a system between those two. There is no distinction between Major and Minor power factor, either. What this allows you to do is to track your progress with a simple time number - and it makes it easy to compare your results to other folks who are shooting the same drills.

If 1.0 does well, I may consider developing a second deck with more advanced, involved drills - it could be shuffled straight into the 1.0 deck, giving you 104 drills in one spot. We'll see what happens...
