Advice for someone who used to RV, stopped for a few years, and needs to rebuild the skill?

When I used to do it I was pretty proficient without even trying. After the first time I heard about RV I did a few targets with some friends that were pretty close, and I had success with the RV Tournament app. With the app, some hits were 100% on target. And sometimes with the practice targets I'd get the following or last target first, whatever that meant.

Skip a few years; I just tried RVT and was bad lol.

Any advice for someone to redevelop their ability? Thanks!
