I try and sling twice a day, which I mostly succeed at. Once in the morning and then again in the afternoon. Most times, two rounds of 12 rocks. Sometimes, 3 rounds but I usually refrain due to the hassle of recollecting the ammo and lack of time. I sling mostly in the local park a walk away.

Regular for me is once a week.  Sometimes I'll get out for a few throws during the week, but usually just a good session over the weekend.

no schedule for me. i always have a sling with me so i get a shot off when i can.
target practice is most common but sometimes i go for distance. 

Twice a week if I'm lucky and I'm not usually that lucky.

right now 0 times per month for the last 2 months.
I wonder what will be the effects on accuracy in 3 months when I believe freedom will be reinstated.

Currently it depends on the weather, and as there is still a lot of snow, it's not particularly convenient. Probably about times a week when possible.

I try to go out in the backyard 2-3 times a day and throw tennis balls for my defective non-fetching dog. I have a target on each end of the yard, since my dog collects all the balls in a pile instead of bringing them to me after chasing them. I get maybe 10-30 throws in before I go back inside to deal with children or something else.

The last time I had an actual slinging routine was back in 2014. I slung virtually every day on my shooting lane approx. 50-100 shots 1 to 2 times a day. It was awesome. No pumpkin or tree stump was safe.

   I used to sling every day when walking my last two Huskies.  When they passed the new crew wasn't as good  on lead so my slinging has suffered.  I need to get back into it. The dogs are older now and better behaved.  I can train them to be slinging dogs now. 

Right now it's 40 degrees and wind and rain. Hard to sling in that. Will be that way for the rest of the month.

I made a big backstop. My kids sling every day, I usually go out and join them for 50 shots or so. Unless it rains, then we just run around in the rain splashing the puddles.

I try to sling every day 150-200 shots.
