How long do y have to wait for your personal chiped ball to return?

You don't hit personal balls. You hit top golf balls that are numbered and tracked for scoring in the various games/challenges they have.

There is really an unlimited supply of balls. You can hit them as fast as you want. We just waited for the score to register before hitting the next one. When you miss a target completely it just waits for you to get you next ball before registering a 0 for the miss.

We have multiple chipped golf balls, so you never have to hit the same one!
