How many reloads on .223 brass?

I have never tracked how many reloads I have on .223 brass.  Typically all of my pickups come from a police range and I can pretty much assume all are once fired with 90% having a crimped primer pocket.  Once I use my reloads that have just been fired twice I place them in the bucket and start over with new once fired.  Due to extreme competition at the range now with a couple of guys who sneak in to sell the brass, I will soon be dipping into my extra buckets.  How  do you segregate the brass ?  Do you guys even worry about it?  Pistol stuff I load until it splits, was thinking of doing the same to this .223.  It's not competition or self defense ammo, only mild plinking ammo.  What do you guys do to mark the number of times reloaded or do you bother?  BTW This is to be fired in multiple different ar platforms.
