Daily when I am home
When I am stateside I carry everyday and when I walk out the door I go straight into the backyard where I have a small target aray set up (My BIG range is in my back 60). I keep two IPSC cardboards posted and two quarter size IPSC steel targets there.
I also have a small ammocan with a few decks of old playing cards all mixed up but face down in it and some spray glue.
I go out every morning, go to the ammo can, pull out the glue and spray a small spot on the target. Then without looking at the face of the card attach it to the target and walk away. Cards have a hit value, Ace is 1, Duece is 2, 10 is ten, face cards represent failures to stop, multiple target engagment, support hand only use, transition to another weapon, etc.
I shoot from a different location everyday and until I turn and identify my threat I do not know how many rounds I will need. Once I turn Identify and engage I am determining my "HIT" count. Not shot count. counting rounds is the hard part not concentrate on. You want to learn the rhythme of your shot strings.
*Note on shot strings (practice a drill called "sixes"). Six rounds, close range, 1.5-2.0 sec (use a timer) from the gaurd and you can cover them with the end of a soda can. Heavy price to pay in ammo to learn this but very worth it. Good trigger reset and follow-through are a must.
You can dress it up with movement drills, multiple targets, utilizing a back-up gun etc.
Then I top off my mag(s) and go about my day. Some mornings I shoot 1 round some days I gotta go back to my home office and get ammo. I buy in bulk so it helps. Also, I know my carry gun works on the ammo I am using. I have seen certain ammo performance with certain guns be dismal while in other weapons working perfectly.
